Familiars losing spells at certain levels

[Torrance]

I know that this is a common problem with a few of the familiar but, for the parrot in particular, I believe it has a Eagle's Splendor at 1-4 and then loses it for 2 casts of color spray.

Is there a way this can be fixed? This has been a pretty long running bug as far as I'm aware.

If someone else knows about other familiars that are bugged, post them in here, hopefully this can be fixed.

Thanks!
