Is there a way to delete or hide Messages sent to MapShare while keeping the Tracks displayed?

I have removed all messages from my inReach device and in "Explore" at explore.garmin.com.  I've sync'd my device.  The device and Earthmate Message pages are blank.  The Explore INBOX shows "People" followed by "You haven't started any conversations yet."  Yet, MapShare still shows the old messages.

The Messages appear to be linked to the User.  When I hide the entire Library and all Collections the messages continue to appear.  If I hide the User, the Messages disappear.  However, the Tracks for the User also disappear.  In all cases for the User, the Message count is zero, e.g., "Messages(0))" is displayed, the visibility icon has a slash though it, and if you click on Messages is opens the form with "There are no messages to display for this user." 

I want to be able to display Tracks from 2018 and 2019.  I do not want to show the messages that were sent to MapShare when those tracks were created. So, simply filtering on the Date is not a viable option.

I'd like to hide or remove the Messages that were sent to MapShare.  I'm ok with permanently deleting the Messages.

I'm hoping someone has a simple solution before I proceed to export all information, modify the data files, create a fresh account, and import only the information I want to expose.

Thank you in advance for your suggestions.

Fair winds,
