Security Compliance Manager 3.0, Comparing Baseline error. "The node to be inserted is from a different document context"

I downloaded a MS 2012 R2 baseline, created a duplicate of that, customized the duplicated baseline as per out infra & locked it.
Ran a compare between the original MS baseline & the customized one. Worked perfect.

I exported the customized baseline in GPO Backup folder format.

Now accidentally I deleted the customized baseline from SCM console, as well as the Original MS baseline.
Never mind I imported the customized baseline back on the tool from the backup I created & again downloaded the default MS baseline.

So now again I've the customized baseline which I imported as well as the original MS baseline with me.
But when I run a comparison between them it gives me an error as " "The node to be inserted is from a different document context"

But if the same imported customized baseline I compare it with any other Original MS baseline, it gives me the correct results without error.

It just gives me the error only when I compare the Customized baseline with it's Original baseline.

Any helps please?

Here's the complete error details:-
