Search Module problem

[garda]

Hello dears,

I've a problem with the Search Module, when using Chrome.
The first search with clean browser cache works correctly.
The second search applies only in the last category visited, whilst it should apply to the whole inventory.

In Search Module options, the Search Filter Category is disabled.
In Joomla Global Configuration the cache is disabled.
THe Url SEF is enabled (I read someone solved by enabling it)

This problems seems to occur only with Chrome, not with Internet Explorer.

My versions:
PHP 7
Joomla 3.8.5
Virtuemart 3.2.12

My website: www.ildistintivo.it if you want to reproduce the problem.

Could you help me, please?
Thank you in advance

In the module, you can set an itmeID, this is the itmeid of a Joomla menu.
Use the Joomla menu item ID link to your root category
