Child theme doesn't load parent modules

[xlynx]

Hello,

I created 2 new themes, both with the "classic" theme as parent. Multistore is enabled and each store has its own theme.
The first theme loads modules from the second theme and not from the classic theme, and sometimes the second them load some modules from the first theme .

For example for the first theme (store 1) with the "chrome  dev tools" I get this :

<!-- begin module:ps_featuredproducts/views/templates/hook/ps_featuredproducts.tpl -->
<!-- begin C:\wamp64\www\presta/themes/custom2/modules/ps_featuredproducts/views/templates/hook/ps_featuredproducts.tpl -->
<section>...</section>
<!-- end C:\wamp64\www\presta/themes/custom2/modules/ps_imageslider/views/templates/hook/slider.tpl -->
<!-- end module:ps_featuredproducts/views/templates/hook/ps_featuredproducts.tpl -->

Theme 1 : 

parent: classic

name: custom1

display_name: Custom1

Theme 2 :

parent: classic

name: custom2

display_name: Custom2

DEV Mode : enabled 
Prestashop version : 1.7.6.7
Tested on other installation with the same issue.
 

Thanks
