The circle component in the “Nord Ultra” master has a leftover attribute. it had a “reversePaths” set to zero. Some code only checks if that key is set, not the actual value.
Select the circle in the “Nord Ultra” master and click the “Reverse” checkbox twice, that should clear it.
There was no way to realize that. I was suspecting something like this and copy pasted the components from another master and then made a diff of the file before and after.
