GT Metrix – Serve resources from a consistent URL

I got problem with i guess PWB. GT Metrix says:

Serve resources from a consistent URL	
F (0)
 	CONTENT	HIGH
What's this mean?
The following resources have identical contents, but are served from different URLs. Serve these resources from a consistent URL to save 1 request(s) and 269.9KiB.

https://vidam.hr/wp-content/plugins/revslider/public/assets/js/rs6.min.js?rev=6.1.5
https://vidam.hr/wp-content/plugins/revslider/public/assets/js/rs6.min.js?ver=6.1.5
The following resources have identical contents, but are served from different URLs. Serve these resources from a consistent URL to save 1 request(s) and 147.2KiB.

https://vidam.hr/wp-content/plugins/revslider/public/assets/js/revolution.tools.min.js?ver=6.0

I guess it is conected to PWB plugin by this:

pwb_ajax_object = {"carousel_prev":"<","carousel_next":">"};
var pwb_ajax_object = {"carousel_prev":"<","carousel_next":">"};
