URGENT : Fetch more than 3 products

Hello,

I’m having a big problem : it seems that I can’t fetch more than 3 products in test mode.
Whenever I try to fetch a fourth product, one the three previous fetched products disappear in my products list :frowning:

Is this a feature of test mode?
How can I change that?

Best,

David

Sorry, it seems that I have the same data-item-id on quite every product (not on my local version, which is weird, but, anyway, I know what to search now).
