Broken Images of Icons in Personal Environment Service Studio

I'm not sure why but the images in the icons selection popup window appears to be broken. 

Currently using Service Studio 11.5.45

This is a screenshot of the issue in Service Studio.


Appreciate any help to troubleshoot and resolve this.

Thanks & regards,

Boney


Yeah, it's a known bug, I'll (again) point OutSystems' attention to this, thanks for reporting.
