Negative adjustment

Options
Hi.

I use Apple Watch for tracking and every now and then MFP app is not working well. I have the negative adjustment ticked, because I use my tracker every day. Any exercise I’ve done has adjusted and increased my calories for that day.
Today it’s - 1560 after I went to the gym.

This keeps happening once I’ve looked at my settings and tried to work it out it’s sometimes work.
Please help.
