Missing Products in feed despite support solutions

Hi,

I have 360 products on my store and 1 category (“poster” category) is missing in my feed.

I have already checked your blog post on possible causes ( here : https://adtribes.io/help-i-have-none-or-less-products-in-my-product-feed-than-expected/ ) without success.

The products missing are variable product. I’ve tried all the possible combinations for those parameters:
“Include all product variations”
“Only include default product variation”
“Only include lowest priced product variation”
And it didn’t changed anything.

I’ve also deleted my browser’s cache without success.

The products missing do have an “id” but they don’t have an SKU value but I don’t think it’s the cause of the problem.

Please can you help? Thanks
