[CONNECT] Multileader Attributes\Text Not Displaying Properly

Hello,

Have a DWG with multileaders in it. Text in the multileader looks like this in Acad 2018 (plain Acad no C3D):

In CONNECT U13 I see this:

After doing a 'Save As' the ### fields scale up about 5 times larger than the clip above.

I do get an Object enabler message about 'RTEXT' in Express Tools, but can't find and Express Tools OE.

This is causing problems in when I create PDF renditions also - I get the ### signs instead of the text.
File attached. Any thoughts?

Thanks
