Automation parameters wrong

Hello, I have a problem with spanner in a different kind of tracks, from LCR to 7.1. I insert the plug in and everything seems to be ok, the initial automation parameters are correct, but after some time working, the automation parameters seems to be moved without reason. Even if I remove the spanner and insert it again, with the inital parameters properly set again, after sometime seems to be wrong again. I attach some pictures.

Thanks.

This is almost certainly the Pro Tools automation lanes getting bad values written onto them at some point. Check the automation lanes and see what’s there.

Other than that you might have a control surface and you accidentally bumped the “width” control?
