Keep losing custom column data

[Sheltered]

Hi, I'm not too clever on Sharepoint just getting to grips with it at work, but I've come across a problem that's a PITA!
We have a document libraby and each document has 2 custom columns which we group and order the documents by to effectively replicate a folder structure.

The problem I'm encountering is that randomly (it would appear) when a document is checked out and back in again the data in the custom columns is lost so when a team member goes to find for example the holiday sheet it's not in it's "usual place" on the library view. Instead it's group under a blank column on it's own and the user has to edit the properties of the document to add back the column data.

Does anyone know a) why this is happening? and/or b) a way to lock the column data?
Any help greatly appreciated.
Thanks
Pete
