how to change instrument (from electric guitar to acoustic) on existing musical score

I use Musescore v4.2.1,240230937 Windows 10 64bit

I made a simple score with Musescore's built in instrument (electric guitar with tablature ). I want to change the instrument to acoustic guitar with tab.

My steps:

1) I right click next to stave that says guitar

2) On left pane under Instruments, I click on settings under electric guitar,

3) Under replace instrument, I picked acoustic guitar with Tab.

I read your discussion forum but changing instrument but I am having difficulty doing it right.

When I click on each note, I can hear the new sound (acoustic guitar) however when I do the playback, I only hear sound of electric guitar but no acoustic sound. What am I doing wrong?
