1\. On schematic of "Project A" I add 3 custom attributes for every component \- "Replacement 1"\, "Replacement 2"\, "Replacement 3" to use them for alternative parts\.
They appear in BOM as expected, everything OK.

2\. On schematic of "Project B" I have not seen "Replacement 1"\, "Replacement 2"\, "Replacement 3"\, so I created them again on this schematic\.
3\. I return back to schematic of "Project A"\. Now I see multiple "Replacement X" parameters in list\!

4\. And what is much worse \- I can not add any of these "Replacement X" to BOM anymore\!
I chose "Replacement 1", fill some p/n to Value field, save changes, open BOM and see "Replacement 1" empty!
