This is not an issue. The hash format changed as mentioned by hashcat:
The plugin 2500 is deprecated and was replaced with plugin 22000. For more details, please read: https://hashcat.net/forum/thread-10253.html
The wiki is helpful, too:

And why the format changed is explained here:
https://github.com/hashcat/hashcat/issues/1816
To solve your problem, just use the recommended tools to attack the target, store the traffic to a dump file (pcapng format), convert it to hash mode 22000 and feed hashcat with it.
Hash mode 22000 combines the two modes 2500 (EAPOL) and 16800 (PMKID) to a single mode.
