I have updated new library and new 2020 Version of Toolbox, I have 2 problem with this new version which I can not work with the software,

1. When I finish my drawing and will nest and create G-Code from my project I can not see any part on processing center page (Picture, ERR-2.NEW VERSION.JPG), but i am able to nest my project with the old version of Toolbox(Picture, ERR-1.OLD VERSION.JPG)

2. With the Solid Modeling page I can not add a door or drawer or something else from the custom tools page to my custom product which I drew by EPB and as you see on the picture it throws somewhere else.(Picture, ERR.3.JPG)

Would you please fix those errors for me? I am not able to work with the new version now.

Regards.
