Old project with new version WFS

I resumed with the latest version of WFS (1.2.7) an old project dating back 6 months made with the WFS version of this date.
WFS tells me that the WatchApplemint font is missing and that it will be replaced by a system font.
All text areas were set to be in sync with device.
I save the project under a new name and ask to rebuild this one, but the compilation stops with the message “font file does not exist”.
I redefine all the text areas with an integrated font in WFS. The reconstruction is going well.
I put these text areas back with “synchronized with device” and this time the compilation ends well.
Do you have an explanation ?


You can see this explanation from Ron.
