Need help correcting a formula to subtract time tracked from planned hours

Hi! Ive searched and searched, and in theory I’m doing everthing right, but I’m not getting the right response.
I have a task for “total monthly hours” and subitems where the time tracking rolls up to that top item. I created a “planned hours” budget in the image below of 12 hours, the “time tracking” shows 1 hour clocked, but I’m getting a result of -3,588 - the result returned should be 11.

I’ve tried both of these formulas and it returns the same result
minus({Planned Hours}, {Time Tracking#Hours})
{Planned Hours}-{Time Tracking}
