Double Line to Ground Fault Model Change

Hi
If you see in the below picture(attached file), double line to ground has been modeled in PSCAD such that there is a Rf between two phases. How to remove the Resistance between the two phases in double line to ground fault case and have only one Rf which is connected from (Phase-phase shorted) node to ground?

You may say that try to do fault analysis manually using switches without using blocks but i tried, it didn't work for me. I would like to know if there is any other solution.
Thanks

As per my understanding, this type of fault can be easily performed in manual without any issue.
Can you attach the file here or the error that you are facing ?

I don't get an error. When I use breakers to manually perform double line to ground fault, the frequency goes very high in some part of the system and goes very low in another part of the system.

Can you share the file or Can you make a simple example file and attach here to demonstrate your observation
