I have noticed that Auto tags are getting created on release branch "release/v2.3.0-10_24". The issue is that the tag name is always same as branch name which causes issues while taking a pull and other tasks.
This is the only branch we have noticed this happening for now. Please let me know if any further details are needed.
FYI : there had been 3-4 incidents where I have seen this issue, and I had to explicitly delete the tag created.
