ExcelAddInName property not respected after restart

I have a custom `` property set and the results after installing it using Options > Add-Ins seems to be two "Active Application Add-ins":

1) with correct custom name (includes version), same xll location, "COM Add-in" type
2) with project name "-Addin", same xll location, "Excel Add-in" type

However when using the Manage: "Excel Add-ins" [Go...] menu, only the second wrong name is displayed.

Do I need to configure it somewhere else?
