I'm using the beta ver and deleted Id clipping warning is showing, I dont find the "null" to delete

[rigid fable]

I deleted some clippings and normally in older ver it would show the word "null" and i'd just delete it
.
but now I'm using the beta ver and deleted Id clipping warning is showing, I dont find the "null" to delete?
should i use the normal ver to fix this or?? there is something i should do to delete the not showing null

[dense charm]

no idea really, at that point I would just set up the clipping again 😦
