Jabref window title does not scale correctly on external monitor

I have an external monitor (1920X1080) connected to my windows laptop as extended desktop.
Primary laptop monitor has a resolution of 2560X1600.
When I open Jabref 5.6 and move the window to the external monitor, everything scales correctly except the window heading title which becomes huge. Any ideas?
