Bug in tag section when i use similar tags

Hi! In 1.29 version, if i have 2 tags with similar terms (example: “Resident Evil” and “Resident Evil: Village”), if i insert two tags, its generate a duplicate in tag section.

And if i try to delete the second tag, none of tags its deleted.

Its as visual bug, because after i published the post its show tags without errors (in stories list and after a refresh the editor)
