Campaign Always Out of Budget

I have an auto campaign set to $50. Today, it has spent $0.87, and it’s already saying it’s out of budget. None of my other campaigns do this, and they are still running. I cannot figure out why this is happening. None of the settings suggest it’s anything but a glitch.

It ended yesterday at about $3.00 spent in total. I was curious if the stats are lagging, but that doesn’t seem to be the case at all.

Any ideas?
