how does this happen?

I play logic puzzles, the 4x5 grid, challenging. Here's what it shows as my May statistics:

Total Played:	6 puzzles
Total Solved:	7 puzzles
Success Rate:	116.67%

Just a guess, but perhaps you began a puzzle in the last few moments of April and completed it in first few moments of May?

I don't know what time of day this would be for you; it would depend on the server time zone and your own.
