Chart - Data Label shows in decimal format vs whole number

Hello,

I have a very simple worksheet.

It has a chart that represents the data from E32/F32

However the data label shows as 2.56 and 0.84 vs. 256 and 84?

I tried changing the format of the cell for the source data as well as the data label with the same results.

It is most likely something simple.

Someone lend a hand?

can you post example file
