I'm probably only going to add to the confusion but I bought a brand new TS430S back in the 1980s. I ordered it with the FM board and I also ordered the 6kHz wide AM filter. It is a long time ago but I recall having a similar experience to you after I fitted the AM filter. I wasn't happy with the way it selected the filters depending on mode.

I think I ended up modifying the switch selection such that it did the following:

AM Wide (6kHz filter)
AM Narrow (2.2kHz filter)

I haven't used this radio for many, many years but I think that is how I arranged it. However, I'm not sure my switch wiring mods added any real value as I only ever selected the (new) 6kHz AM filter in wide mode anyway. I was a bit disappointed with the new wide AM filter. I think it would have been nicer if it was 8kHz rather than 6kHz wide.
