Additional context
Doesn't seem to just be a visual bug, APIs seem to think that it's -100% too

It's written as "-100% off", which would be equivalent to "100% more"

OK, that seems kind of confusing when the sale page normally says -100% for a sale and 100% more for a reverse sale. Is it deliberately confusing as part of the "April Fools" theme of the reverse sales?
