Photophatch problem with loading watermark inages

[s.merlin]

I can't find a solution for the bug in Phatch 0.2.7 installation after upgrade my OS to Mint 18.
The problem is, that i try to open the drop down menu in Watermark Module and it isn't possible. Only it says LODING.
I can't choose another image for watermarking.
Do you have any idea what i can do?

regards

Sven
