hashcat online converter run cap2hccapx from hashcat-utils.
You should know that cap2hccapx will convert more than one hash to the hccapx file. Therefore it takes every good message pair and convert it:
Code:
$ ./cap2hccapx.bin ptcl_l2-test-01.cap test.hccapx

Written 15 WPA Handshakes to: test.hccapx
Result is a single hccapx file that contain 15 hashes from your BSSID!
I noticed that you ran airodump-ng in combination with aireplay-ng to deauthenticate the client. In that case you must expect a packet loss, because neither aireplay-ng (active part) nor airodump-ng (passive part) request missing packets. Additional your cap file contain many, many useless frames.
Also, you have made much noise on the channel to get a few hashes:

If you take a closer look at the converted hashes, you'll notice that hcacpangtool converted different "best" hashes (a PMKID send from the access point to every CLIENTS and an EAPOL messagepair).
Running hashcat against them will recover the PSK quickly (and without any additional options):

Three times from the PMKID and one time from the EAPOL messagepair.
BTW:
You may have noticed that the new hashline is HEX-ASCII. You can use simple bash commands to show it, to sort it and to remove unwanted hashes.
A single PMKID is more than enough to recover the PSK. You can remove the other hashes.
should I use this --nonce-error-corrections=128 in my batch ?
-> that question isn't easy to answer, because it depend on the tools you use to atttack the network, to capture the traffic, to convert the hash and to recover the PSK.
But hcxpcangtool will help you a little bit to choose the nonce-error-corrections values. This is the measured value between the lowest replaycount and the highest replaycount:
REPLAYCOUNT gap (measured maximum).......: 23
Always, you can use this value for hashcat nonce-error-corrections to be on the safe side.
Running hcxdumptool to attack and capture, hcxpcapngtool to convert and latest hashcat to recover the PSKs will give you good results and less noise on the channel (PMKID attack:
https://hashcat.net/forum/thread-7717.html).
If you have a PMKID, use it (hashcat old hashmode -m 16800 or hashcat new hashmode -m 22000). Don't waste your GPU time on EAPOL messagepairs (unless you like to discover the secrets of an unauthorized M2).
If you retrieve the PMKID by hand (Wireshark), keep in mind that it can be calculated using a zeroed PMK!
If you run hcxpcapngtool, you will be informed and this kind of PMKID will not be not converted:
PMKID (over zeroed PMK)..................: 1
Additional hcxhashtool will give you an information about the ACCESS POINT, the CLIENT and the state of the authentication:

By option --all, hcxpcapngtool will convert all PMKIDs and all EAPOL messagepairs. That included many duplicates, but hashcat recovered the PSKs successful from them, too.
In that case you should use at least nonce-error-corrections=8 to recover all PSKs.
