Hello happy ARKers!

Has anyone had an issue with not being able to put a saddle on a Legendary Quetz? We tamed a Legendary Quetz (red glow) and opened its inventory to add the saddle, but the space where you normally see the saddle/costume box looks as if I were in a regular fabricator inventory. I've seen in a video, I should be able to toss a regular saddle on it (granted, it's an older video)
I've tried E (still gives the "press E to saddle" text), F for inventory, holding E for the circle menu and selecting "saddle", putting the saddle in its inventory anyways, both a regular and a platform. No saddle box on the right, just looks like a fabricator inventory.

Is this an issue with the Legendary Quetz or an isolated issue (could I be that lucky? :) hehehe!)

Thanks for any help!
