Back Template has a problem

[pcchoon]

All the cards were working fine and I do not really understand what happened.
I search the forum to see if I could solve this but nothing seems to work.

Back template has a problem:
Found ‘⁨{{Learning Outcome}}⁩’, but there is no field called ‘⁨Learning Outcome⁩’
More information

This error occurs when a field that is referenced in the template doesn’t exist.

Have you already checked whether you have a field called “Learning Outcome”?
Perhaps it was renamed?
