Products Images list on product page PS 1.7.8.7

[ZiedDams]

Hi guys hope you doing good

im working on prestashop 1.7.8.7

my problem first was the product image cover is not displayed in the product page

i corrected that by changing the 

$product.default_image

to

$product.cover

but still the other images not listed i debugged the variable

$product.images

in the loop

{foreach from=$product.images item=image}

and it is empty !

meanwhile in the back-office the product has more then 1 image

i also change the cover image of the product and return it to the previous one from the BO then all the images displayed fine .

but i cannot do this for all products so is there anyway to solve this issue please .

have a good day .
