Doesn’t work at all – Product selector Review

I’ve been using the Axis product selector for quite a long time, and it’s worked perfectly. Recently it doesn’t return any products at all. Before when it was opened it showed Axis’ complete product line, and dropped products as various filters were added. Now it reports “no matching selections” as soon as it’s opened. Adding filters does nothing to display selections.
