Pompeii world errors

In running the code for the Toybox of Pompeii/Mt. Vesuvius, instead of providing the chat comments programmed into the code (i.e. the temperature has reached 120 degrees), it just "whispers<>block cannot be placed>> The program still is running as the volcano is still erupting, but the chat information isn't portraying and it just repeatedly announces blocks can't be placed. I have the 1.20.13 version of MC Education---which looks like the latest version. Any support would be appreciated. Thanks!
