Problem with JS load by Google Mobile Friendly tool

[kam0200]

Hello, I am using Google Mobile Friendly tool to verify if all is ok  : https://search.google.com/test/mobile-friendly

and for example for this product : https://sklep.agropilot.com.pl/ciagniki/czesci-zamienne-do-ciagnikow-ursus/czesci-zamienne-do-ciagnikow-ursus-c-360/czesci-zamienne-do-skrzyni-biegow-ciagnika-ursus-c-360/33943-uszczelka-korpusu-skrzyni-biegow-tylny-most-pasuje-do-c-360.html

General results is OK that website is optimized for mobile but I have few errors with JS load

 

In result this tool complains about load files , not always but sometimes, sometimes there are other files there also some images:

https://sklep.agropilot.com.pl/js/jquery/plugins/jquery.idTabs.js

https://sklep.agropilot.com.pl/js/jquery/plugins/jquery.scrollTo.js

https://sklep.agropilot.com.pl/modules/ganalytics/views/js/GoogleAnalyticActionLib.js

https://sklep.agropilot.com.pl/modules/x13askaboutprice/views/js/x13askaboutprice.js

 

Do you have any ideas tips what could cause that ?

I have option in performance turned on - move all JS to the end.

Is this errors caused by some order of scripts load ? I tried to manage some modules and placed in them at end by managing hooks but not helped.

Is that something about robots.txt ?

Thanks

Kamil
