Been trying to create a tag system, but when i try with bots they keep getting stuck

Hi! I have been trying to create a tag system for a game im making, and whenever i try out the code, the bot that has the tag just follows 1 other bot and they just keep tagging each other and ignoring everyone else. All other bots just runs to the border of the map and then stops. I have been stuck with this for a while now and i have no idea how to fix it. Also not sure what screenshots to upload, so please let me know wich screenshot to send!

do you use booleans for the tag system?

This is blue code for for the tag itself

Going to write that in proper english. This is the blueprint for the tag.
