Map Name Keeps Reverting Back

(Posting here since no one even tried to help me in the Support forum) So I made a forge map I don’t know how long ago and named it simply ‘Island’. I then wanted to change the name, so I changed it to Litore’tæluði (Beach Planet)… The name stays for a while then it reverts back to ‘island’ for no apparent reason, can anyone help me out here???

p.s. I’ve used other names and the map name still reverts back to ‘island’.

Please don’t cross post topics thanks
