New for 2021 the Band-in-a-Box for Windows mixer has a Settings tab. The second setting is "Load Mute and Solo States with Songs".

If you are using 2021 Band-in-a-Box for Windows, check the value of that setting, checked (enabled) or unchecked (disabled). Reverse the setting and then test to see if that makes a difference for you.

Please update this thread with your results.
