Filter on search results pages does not work

Hello!
Thanks for the great plugin. Everything works fast.
But there is a problem. If we search for something, go to the search results page and try to filter the results, then the filter returns “irrelevant” results.

For example:

https://www.amzsupply.com/shop/?s=mailer&post_type=product&filter_color=red&type_aws=true
We should get red mailers.
But the result is not correct.
But if so – https://www.amzsupply.com/shop/?s=mailer&post_type=product&filter_color=red
Everything is correct.
If you remove &type_aws = true from url, then the filter works correctly.

This problem is only on the search results pages.

How can we fix this?
Thank you
