This is now actually a praise, I like to get out - no problem or similar.
I found out that switching between templates restores the values that one has entered before.
In my case I had a big test cases, that I switched to an automated test case, for which the template only links to the automation and has no description of the steps. I was afraid I need to re-enter all the steps again, but switching back to the previous template restored all these values.
That is really nice and hurray for that
