Calc does not notify the user when the template has changed that a document is based on. This works perfectly well in Writer. It also used to work in Calc in 3.x.
It did notify me: The template 'calctest' on which this document is based, has been modified. Do you want to update style based formatting according to the modified template? Perhaps you need to try this trick: https://wiki.documentfoundation.org/User_Profile#Resolving_corruption_in_the_user_profile Set to NEEDINFO. Change back to UNCONFIRMED, if the problem persists after further testing. Change to RESOLVED WORKSFORME, if the problem went away.

Thank you, Beluga. I followed the instructions from the Wiki to reset my user profile which solved the problem.
