Cannot post budget entries "Changes have been made to combination #####-## since the combination last used"


I am trying to post basic budget entries in AX2012 R2 and get the following message:

Changes have been made to combination 44127-070 since the combination was last used. The combination must be re-validated to be used."

I found a blog that mentions that I go to the GL/Setup/Chart of accounts/Account structure and find the structure that has this account. I then click Edit and then validate and close. This did not fix the problem. What else can I look at for this issue?
