When doing a search, and attempting to add AC (Atwood-Coffee) in the reference box it automatically goes to KM. Some other references I tried came up fine. Just Atwood Coffee seems to be the problem for me so far. This is on my phone. Have not tried on my desktop.
I did an initial investigation of this issue. The search “AC” returns 48 catalogues, including AC (Atwood-Coffee) and KM (because the publisher of Numismaster is Active Interest Media). If you scroll the small box containing the list of catalogues up to the top, you will find Atwood-Coffee. What is unusual here is that the list of results is usually showing the first results first. But because KM was pre-selected before your search and it is part of the search results, the list gets automatically scrolled down to KM.
Thank you for looking into it. I could use AC to quickly get to the reference in the past. It only recently started doing it. Only reason why I posted it as a bug.
This might be important, when type AC from the features section to add the reference it doesn't work like it use to. As described above. But, when typing the reference AC in on the date line section it pulls right up.
