Error while exporting SNAP to PolSARPro

I was exporting stacked SLC S1 data into PolSARPro format and i have encounter following error. Can anyone recommend probable solution and reason of this error.

org.jdom2.IllegalNameException: The name “Master: 03Mar2019” is not legal for JDOM/XML elements: XML name ‘Master: 03Mar2019’ cannot contain the character "

I am facing the same problem. Could any please suggest a solution.

Maybe you just have to remove the space in the dim file at the mentioned line?
