Admin catalog search doesn't work

[MailisAmalric]

Hi,

I'm working with Prestashop 1.7.8.7 and the theme Bigsoho - Super Mega Store

I have problems with products search / filter in the admin.

I can change colum sort but when I add a reference, a price or other filter in the form, filtering doesn't work.

In front it's ok so I think it's not an indexation problem but I don't understand why I have this issue.

And the SQL query doesn't contain the good where clause as you can see in the screenshot.

Could you please help me ?

Thanks a lot and have a nice day !
