Unable to schedule LMS story

Hi everyone,

I've tried to schedule a story with a table from LMS but keep getting this error:

I've been unable to schedule anything regarding LMS. I've also tried to create a story with one table from EC and one from LMS and schedule only the LMS one, but I get this message:

So, it looks like the schedule planner doesn't recognize learning widgets. Do you know if this is a solvable error, or if this is a known issue that will be covered in future releases?

Thanks in advance and kind regards.
