Pimcore loses Data


i’ve got a problem with one of my objects in pimcore. It seems to forget all data that is either stored in one oft the 3 maps included or in the localized fields (we are using over 15 languages). In the version history the stored data is displayed but not in the object.

I’m working on this new system for our company now for a few weeks and have never used pimcore or php before. Still i’m able to programm most things in php as i used to programm other languages before.

Thank you in advance
