Account lines in the Budget screen that are marked with a + and do not contain any numbers or zeros, have been nominated as linked accounts in the Cashflow Settings.
Calxa is automatically calculating a Budget for this account for you
If you wish to add your own budget manually, first you will need to remove the account from the Cashflow settings.
Note:
Some settings MUST have an account nominated, and if you deselect an account it may need to be replaced with something else.
