I've created a template and have marked the features indicated below as "Locked: Allow text replace".

When I share the template with others, the 'Locked:Allow text replace' unlocks and if I go in to lock it again, other text numbers become unlocked. How can I prevent this from happening? Please urgently help as this is for work!
