I had this same issue as well, but I found a fix on their website:

"On some systems, Zafehouse: Diaries may display visual anomalies, such as corrupted graphics or invisible text. The game comes with a “Diagnostics Tool” that allows you to turn on certain compatibility fixes to address these issues.

The tool can be found in the “Zafehouse Diaries” program group, or in the game’s installation directory as a file called “ZafeDiag.exe”."

When you check a box and save it in ZafeDiag, you need to also press the Generate MD5 Hashes button and it'll truely save it.
