Version 10 is many years ago, but I'll try.

First, when you change the patch for the melody instrument, do a File, Save With Patches & Harmony and - Here's the Tip - make sure to do this command while the song is still playing.

Second, some styles have patch changes built in. If the tip above does not work, then you will need to go to Options, Preferences and find the MIDI option menu for version 10 that says something like Allow Style Patch Changes, and uncheck that checkbox.

There is also a Global Override preference for this in later versions, but I'm pretty sure version 10 did not have that.

Let us know if this works for you.
