Trying to delete remote branch which has the same name as a tag causes error

When attempting to remove a branch from the remote server which also has a tag with the same name, for example "feature/AutoPublish" as the tag and the branch name, this causes an error because there are 2 with the same name matching in git causing the command to fail.

The screenshot shows the output from sourcetree related to this, the command does not seem very specific to the fact that it is deleting a branch, is this potentially the cause of the problem?

Thanks
