error amp pages

if you press enter looking for something generate this url:
https://atremorine.proasalud.com/?s=atre&post_type=product and there are a conflict with my plugin for amp pages because generate https://atremorine.proasalud.com/?s=atre&post_type=product&dgwt_wcas=1?amp?amp?amp?amp?amp?amp?amp?amp?amp?amp?amp?amp
I think that the problem is this in url &dgwt_wcas=1. Its posible eliminate this part in the urls?
