How to clear export_module for a view
After removing MODULE-Name_views_default_views() in file MODULE-Name.views_default.inc, the view was exporting in another feature/module just fine.

My learning is that if you rename views that are part of some feature/module say X then these views become impossible to export from any another feature/module Y unless you manually delete them from the MODULE-X-Name_views_default_views() in MODULE-X.views_default.inc file
