Issues with with editing records in Contacts module.

Hi,

We are using the following URL when accessing records in "Contact" module:
/?module=Contacts&return_module=Contacts&action=EditView&record=a20a1d46-70da........
After we click on "Save" 
https://monosnap.com/file/RZcn9KZhz9Aov8PX1Ana8l9axPchSZ
we see this error:
https://monosnap.com/file/MLvsLlCb9vYFPKTRO11mRLtmCX2Sfk

As you can see the record ID is not being passed. 


Has anyone encountered something similar? How we can avoid it? Should we use a different URL to edit our records?
