Open Food Facts differentiates between "nutrition facts for the product as sold" and "nutrition facts for the prepared product". Most products only specify nutrients "as sold", but for certain items (for example pudding powder), it's much more interesting to get the "prepared product" nutrients as I don't really care how much fat/salt/etc. is in the powder itself. After all, I'm not going to eat the powder but the prepared pudding...
When I try to scan the barcode of the above product with Waistline, it says "No matching results". Apparently, you are only checking for the nutrients "as sold" at the moment; and if a product doesn't have them, you ignore it.
I think if an OFF product comes with "nutrition facts for the prepared product", Waistline should use them.

In fact, here is an example of an OFF entry that only specifies nutrition facts for the "prepared product" and has no information about the product "as sold": OFF website: https://world.openfoodfacts.org/product/8710604724739/spaghetti-alla-carbonara-knorr OFF API link: https://world.openfoodfacts.org/api/v0/product/8710604724739.json
