i have this glitch in digimon world 1 which is i can't train my digimon in green gym یا anywhere, and if it dies یا i change the name it gets stuck!

i got 3 CDs and had the same glitch!! is that suppose to happen? cause i heard that it can also get stuck سے طرف کی playing giromon's jukebox. if so, does it depend on the digimon that i raise year, دن یا record? right now i currently have a Megadramon, i'm intermediate level 4 and raised 5 digimon, although i don't remember the time, but its extremely hard to get a high status without training and poor on bits. btw believe it یا not i opened the entrance to MT.
