Inconsistent library searching behaviour

I am encountering what appears to be a bug in the search.

If I go to the Search section, a previous value is in the search, so I remove it and add some new text, then press enter, but the search function does not do anything. To get it to search, I need to change the dropdown selector to TIDAL (or something else), then change it back to Library. After doing that it will search on my library again.

I am using the Bluesound desktop app, on OSX - with Node ICON and Node 2i.
