Can't add two separate paypal subscription buttons on same page

Hello, 

I have created 2 different subscription products in Paypal, with 2 codes, but when I add the 2 codes on sqaurespace on the same page, only one will show up. Both work, and both will show up separately, but if I try put 2 blocks with the different codes, only one will show up. Can anyone tell me how to rectify it?

Thanks so much

Paula
