I don't know what to tell you, Kerry. The manual does talk about the A/P disconnect on pages 194/195, including the audible calvary charge and associated warnings that come with the sound. So, given this, you could have either read the manual or contacted us to say "I read the manual but am not sure where the A/P disconnect button is." I'll say that it doesn't mention the sound clearing with it, but considering the sound is part of the annunciator warnings, this is what is to be interpreted. Instead you came on here asking (and even insinuating) if the sound was a bug, when the manual clearly discusses disabling the warnings (indicating it is possible). To quote the manual: Overall it's not a big deal, and I suppose some take it for granted, but pretty much every aircraft (as Philipp has stated) works this way or similar, so I think it's easy sometimes for us to assume anyone purchasing an add-on this serious would know it. We'll try to remember to be easy, but you also need to remember that in a digital age where words are stored in online search engine databases, labeling things as "problems" which are really not can be damaging.
