Hi, I am using Sketchup Pro 2025, version 25.0.660 64-bit. I wanted to try snaps for the first time and had no problem adding one. The issue is that I can not Edit or erase it, only “Add Snaps” is available :
Select the snap(s) you want to remove and press Delete.
Thanks a lot, Dave! I tried in a new project and it worked 
, so I realized there was something wrong with the first one. When I made all the tags visible, I was suddenly able to select the snaps. Instead of being ‘Untagged’, they were on a hidden tag… I don’t remember selecting this tag when adding the snaps, but I might be wrong.
It would be interesting to see the model with this situation. Edges, face, and snaps should not be given tags. Only groups and components should have tags given to them.
Do you sometime change the default tag from untagged to something else? That can cause confusing issues later, such as you encountered. There is almost never a need to change the default.
No, default tag is untagged.
