Issue with managed transform rules

I am unable to enable more than one managed transform rule on one of my domains. If I enable a second one, the currently active rule gets automatically disabled!

I have recorded a video of the issue here: (!Agb9xGEOXV4l2gDpqOJylq7O5C1V?e=8gMWOu)

I haven’t faced this issue on older domains, though now I am afraid to test anything! Much appreciate any help regarding this.
