Use a more reliable software such as hcxdumptool which is better integrated with hashcat. You don't even need to acquire handshakes necessarily anymore. Unless Wifite is cleaning the caps, then that's the only potential issue.
If you're able to crack a single handshake, there is no difference having multiple handshakes in a single file, the only thing that will change is the time to crack.
Without seeing your hashcat command & log there's not much else we can help you with. Post something like this.
Code:
hashcat64.exe -1 ?d?H -2 01 -m 2500 -a 3 -w 4 capture.hccapx 2511?d?1?2?1?d?d?d?d

We need to see if you're actually attacking 7 different handshakes by checking the recovered line.

I know that capturing PMKID is enough so not need to capture 4-way HS. It really seams, that Wifite2 is not cleaning "incomplete" 4-way handshakes.
