Issue with creating default eyes

Greetings, I really need your help. I'm trying to make some default eyes for pets. But my swatches only add to Maxis ones without replacing them. And now, after my fiftieth try (lol) they all just disappeared - zero swatches, no Maxis OR my default. I've read a few tutorials here, didn't help, so I decided to ask. Here is the file which provoked disappearance: www.mediafire.com/file/8xsdhct4lzhks0p/DodEyes.package/file
Thanks in advance!
