Cannot save existing file
Most of the time when trying to save an exisiting file, InDesign instead tries to Save As.
The file name appears greyed out and can't be selected, and when trying to save the document with the same name the following error appears.

This only seems to happen when saving to a network shared drive, as I cannot replicate the issue when saving the machine. We have checked file permissions and cannot see any issue there, there is also the fact it will sometimes save the file without this issue.
I have noticed a .idlk file appears in the folder when it prompts to save as.
