Meeting reactions not displaying for a colleague

I have a colleague who wants to use the new reactions, however she can see them and select them but they don't show on her video, AND she can't see them if other people in the meeting use them. I've checked her settings, they're all selected, she's on the latest version of zoom. doesn't matter if it's her meeting or if she's joining one. She can see the original ones and they display in the video panel. 

weirdly I can see them when she selects them but she can't ! Any ideas?
