Having issues with the email builder, specifically with adding product:

I have the product block inserted into the email, and I’m adding static products, not a product feed. You can select how many products are in each block, and I’ve selected two. You can see below, the setup is correct - but it will not let me add a second product to the block. When I do, it simply replaces the first product. 

I’ve tried adding multiple products at once, and it also only brings in one product into the product block.

I was able to successfully add multiple products to an email last week, and now I’m unable to. Any help would be appreciated!
