Hello,
it seems the library manager compares layouts by names and not be internal ids or similar. Choose any project A and compare with another project B. Within project B, I have two layouts with the same name (reason for the issue).
Now, when I compare project A with project B “Layout 1” (first occurrence), and then with project B “Layout 1” (second occurrence, same name), I always get results from “Layout 1 (first occurrence)” but never from the other layout. Workaround is to rename the second layout, but as layout name is a variable used in templating, I need to have it this way and consider this a bug.
Thanks!
