incompatibility between wp seo and gravity forms

Hello everyone
I noticed this little problem, if problem you can talk.

I was trying to dynamically populate a form created with gravity form, through quarysting ..

http://www.site.com/langinpage/page/?var=xxx

But this was not the case, even if this type of auto population is managed natively by the plugin quoted above.
The fact is that in order to read the variable to the form I had to disable wp SEO by Yoast. this I am very sorry because creado strongly in this plugin.

I ask for so if you know how to overcome this minor inconvenience. as the auto population for me at the moment is vital, but I would not erase wp by Yoast.
