Stereo Tool

I apologize if this has been asked about before - I spent a long time searching the web and this forum and most likely did not use the same wording as I came up empty with each search.

I have been using MediaMonkey and Stereotool for a couple years now and one thing I see and am unable to determine why is StereoTool is listed twice in the Tools-Options-DSP Plugins menu. I have not seen any functionality issues and am wondering if this is a common issue or unique to my installation. I have seen this with version 3 and 4 of MediaMonkey.

I did a clean install of MM4 (blew everything away and let the new install recreate databases, etc.) but the double entry persists. I am noticing playback issues now and am wondering if it is linked to the double entry.

My apologies again if this has been addressed before. I have found my search techniques to be out of sync with what everyone else.
