A minor bug in the export file generated from the front-end page using: Membership Pro » Subscriptions Management
OSM_SUBSCRIPTION_TYPE is exporting with the field name as the column heading rather than the field label.
I.e. Should be "Type" but has "OSM_SUBSCRIPTION_TYPE"
Thanks Stephen. I added the missing language item to frontend language file and the issue is sorted now. You can download latest package from My Downloads section, upgrade it to your site and the issue will be gone
