skipping file: (null) (invalid eapol size)

[Rdgeno]

I'm using Unbuntu 18.04 ,and I finally have Hashcat up and working as far as I know, but I keep getting, Skipping file: (Null) (Invalid Eapol size). If the size of the file matters then one is 1.28 kb and the other is 786 bytes. The command I am using is Hashcat -m 2500 -a 0  /Home/my user name/the hccapx file/ /home/my user name/ crackstation.txt. The only thing I could find about this problem was that the file needed to be converted from .cap to hccapx I did that and I am still getting the skipping file null invalid eapol size message. What can I do to fix this?
