Could potentially not be a bug and I'm el stupido, but it certainly looks like it.

After contracting an Apus, I'm suddenly not able to summon any youkai besides that Apus.
I do NOT have Contract Uno (or Tres for that matter), and I have the FAI to summon both or either of them, but for some reason my Izabe is practically deleted from my lineup. She is not dead, and even when Apus -is- dead, I can't summon her. The option is grayed out, and without text as well. Some people more knowledgable than me about mechanics in the Korvara OR Sigrogana Discord couldn't say it wasn't a bug - and Miller said it's definitely a bug, just a rare one.
It's also probably worth noting that I can still use fairy lance DESPITE this.
I can't test whether or not getting rid of Apus will fix the problem - or at least, I'd really prefer not to, given the problems of getting to the Apus statue in Korvara and the lack of a public test server for the moment.
