I’m trying to train the Summoner Feat “Skilled Partner” for my Eidolon, and it’s preventing me from acquiring the feats that I already have for my Summoner. It doesn’t say that there is anything that would prevent from acquiring these feats on my Eidolon, per the rules. Let me know if I’m missing something, or if this is a genuine bug.
Hey eechu7, welcome to the community. Can I get a link to your character sheet so I can look into this a bit more closely?
Here you go. Let me know if that didn’t work, as I’ve never linked my character sheet before.
That worked perfectly and I see what’s going on here. It looks like we don’t fully have support yet for the Skilled Partner feat. The skill feat that you’re being asked to select is actually the skill feat for your character rather than the skill feats provided by the Skilled Partner feat. This is why it’s not allowing you to select feats that your character has already selected.
At the moment I’d recommend using the Notes tab to record the skill feats you choose for your Eidolon and I’ll pass along the feedback to our dev team that this isn’t currently working as expected.
Thank you for confirming that something wasn’t lining up! 
Looks like this should be fixed now! Let us know if something still doesn’t look right though
