Hi,
I’am encountering this issue regardless of the value of “HIDE IF BLOCK IS NOT SELECTED”.
I know you said to update WordPress before posting here but I am working on a project created by other people with quite a complex setup and updating to 5.9 breaks everything as this setup is based on the older Guthenberg so maybe this is an incompatibility issue with 5.8.
That said I had the 2.3.1 version and everything worked fine but now we need the new version with the WPLM integration.
I hope you can help me with this issue, thanks in advance
