Export different than playback

Having trouble with LMMS? Ask about it here.
The export of a recent piece of mine has unusually loud bass (bass boosted, not bass as in instrument), much louder than in the playback. Any idea how I could resolve this issue?

That is the key here, and This is so strange that i need to see the project
upload the project, AS MMP! -and send me the link as PM (just right-click my name in byline and choose Contact musikBear), i will take a look at it. If you do not care about copyright, you can upload the project right here, as an attachment, that everyone can see..

To Save as MMP:
* Open project
* File | save-as
* chose a name... 'xyzzxy.mmp'
press save
You can upload on any file-host like google drive
I will ofcause respect your rights
This can be related to the use of certain effects.

For example, there is an issue with Calf Bass Enhancer: viewtopic.php?t=25726
