Unable to deselect email subscriptions?

Hi, I was looking at the Manage Subscriptions page of some of my other accounts, and noticed that in all except my main account, I couldn't select/deselect the email column.

The only commonality I could see was that all my other accounts are non-paid. But I'm not sure that this would be the cause, especially since there have been no reports of this on the board...so I'm trying to gather more data. Anyone want to test?

All you need to do is:
1. Log in to chose account
2. Go to Manage Subscriptions: http://www.livejournal.com/manage/subscriptions/
3. Note whether you can select/deselect anything in the email column
4. rinse lather repeat 1-3
5. List the account names you tried each on with the results (also include account status [paid, basic, plus], or if you see anything that the accounts with each behavior have in common...)

Update:

Oops! They're disabled because my test accounts are not validated. It's even in the FAQ. *silly* Thank you for testing, lied_ohne_worte <3
