Prevent auto-switch to MP3 and MKV when dragging MP4 video?

[pstein]

Assume I started Avidemux v2.7.3 with the following values in the drop down menus at the left side:

Video Output=copy
Audio Output=Copy
Output Format=MP4 Muxer

Now I drag & drop (from Windows Explorer) a *.MP4 video onto the Avidemux window.

Much to my surprise Avidemux always switches automatically to the following values:

Video Output=copy
Audio Output=MP3 (lame)
Output Format=Mkv Muxer

This is annoying.

How can I prevent this auto-switching?
I (always) want to keep the current values.

Probably a combination of "Revert to saved default output settings on video load" enabled in preferences and the above configuration saved as default ("Save current settings as default" in the "Edit" menu).

Works.
