Adobe Stock plans page: credit packs not changing from 40 credit packs to any other numbered packs

Hi,

I'd like to report a bug, that in the plans page, I can't change from 40 credit packs to any other numbered credit packs in my browser. I've tried two different browsers, but still, the problem occurs. I still use Windows 10. I'm unable to buy 5 credit packs.

Just about a week or two ago, the plans page worked fine, and I could change the credit packs and buy the credit packs normally. But now I can't change them.

Please, fix this bug. Thank you very much!
