If it is irritating or concerning to you, you can always use the magic cheat... testingcheatsenabled true. After use, you can use setfamilyfunds householdname amountofmoney. (If the code is wrong, type in help, a little code I used when typing random things after my game would not quit in The Sims 2)
Example:
Setfamilyfunds Nutellasauce 500.
Hope this helps? x3
