Im currently using version 1.14.4.3 and tried to create a template using the /parseruin command. My test-build had a sign, some item-frames, a chest with some items, etc. in it.

After saving it, i spawned it using the /testruin-command and the item-frames were missing, the sign didn't have any text on it and the chest was empty.
