Disappearing block

Description

Found a bug with disappearing blocks. I'm not sure if it is caused by this issue or the conversion to json, but this is the first time a noticed the bug.

Go to https://pi-integrated.e-activesites.nl/test-page
Add two columns
Put the block "Zoeken" in the left column
Put the block "Zoekresultaat" in the right column
Click Save
--> blocks are saved
Click Edit
Click Save
--> blocks disappeared

All blocks in columns seem to disappear after editing
