Critter won't answer rancher's call for grooming.

I've been getting this as well, with just a single Drecko stable, though I also have Hatch stables, and I sometimes see it there as well.

Update: with my drecko stables, wrangling and releasing the critter that's excited but not jumping onto the table temporarily fixes it. I have one smooth hatch stable where none of the hatches ever even get excited, and some of them get this weird empty status effect, which goes away after wrangling, but immediately comes back.

 

There's a potential fix for the empty status item currently in public testing, which appears to be fixed. However, there's another issue where some critters sometimes get stuck animating but have the "Excited" status item.
