Describe the bug
I am using NINA with Paramount MX6 mount connected via ASCOM driver. I have configured NINA to stop 15 minutes before the meridian, and resume 15 minutes after the meridian. NINA starts the meridian flip sequence as expected, however it doesn't actually stop the tracking. Mount continues to track even though NINA has allegedly issued a stop tracking command to the mount. I have to intervene manually to stop the mount in TheSkyX software or it will run into the pier.

Expected Behavior
NINA stops tracking before during meridian flip sequence.
