Unable to remove or edit holograms

[Arton3mis]

After my server restarted I am unable to edit or remove the holograms I already created.

Send the whole server log and a list of plugins/mods you have installed. Then backup the whole server and start to remove half of the plugins/mods and test if the issue still persists. If yes, remove half of it again. If not, test the half you just removed to pinpoint which plugin/mod is causing this.
