Incorrect numbers in LO Calc 5.0?

I blew away my profile, launched a new spreadsheet, and typed in “=500/15”

The answer shown: 3.3333333 Off by a factor of 10.

Converting the cell to scientific notation shows the correct answer: 3.33E+01. But this is not an adequate workaround.

Anyone know what’s going on? Thanks.

EDIT: after playing with it some more, it appears to be a display bug:
