Problem:
The user has a map inside an archive template that gets removed whenever a filter is changed.

Solution:
The Map Block was set within the Search Block of the archive template. And the archive template was configured to display filter options that produce results. When a filter is changed, the whole Search section gets updated and the Map within it is removed.

The Map needs to be put outside of the Search bloc, or the Loop block. Check the screenshots here https://toolset.com/forums/topic/map-disappears-when-filter-is-selected/#post-2162775
