Securities Value amount updating improperly

I am updating an "investment" account manually. I have never set this particular account up online. When adding 'intinc' the "securities value" amount changed but there is no transaction in the register. I do not have any securities for this account, I have just been recording everything as "cash". When I go the "investment" tab to look at all my securities for this account, only cash is listed. Yet, I still have an amount in the "securities value" that is increasing the overall value of the account. I can't find anything in the register to delete. Any thoughts?
