I tested this by exporting the song demo for "ZZJAZWAL.STY" to musicXML, and it looks like it correctly specifies the time signature as 3/4.

Here is the file I got:
https://nn.pgmusic.com/pgfiles/support/misc/ZZJAZWAL.XML

For example, on line 75 it specifies 3/4 for the Guitar part on measure 1, which is what I would expect.
<time>
<beats>3</beats>
<beat-type>4</beat-type>
</time>

Perhaps you could look at or test this file and see if it behaves as you would expect. It might help us find where the problem is. Note: You can view the file with any text editor, like notepad.
