flexbox table, all divs aligned but one, the borders don’t match, don’t know why

I’m doing this table using flexbox, every border matches, but as you see in the fiddle, the second table, the cell with the text: RIGHT SIDE NOT ALIGNED has the border which is not perfectly aligned with the border of the row below!


Tried everything, going crazy, any solution? I did the exact same thing as for the upper table, and there it works without problems, no idea what changes between the 2 tables..

thank you
