Time tracking with negative times

[janeschindler]

For some reason after I deleted the amount of time spent on some issues (which we agreed to do for free after I'd tracked them) I get an incorrect negative in my report. Am I missing some option?

Here are screenshots:
The issue itself with all time removed (first I used /spend with a negative value, then I realized there was such a thing as remove_time_spent).

My gtt report:

Same here. Confusing. How do I filter it out from the report?

On a second thought, the negative number shows up for me in the time records table only I believe indicating that the previously entered spent amount has been removed. Maybe useful after all.
