pivot chart from pivot table reading one wrong cell

Hi

I am using excel 2016.

I have created lot of pivot tables before but never come across this issue before.

Created pivot table like this.

Product SLA Outside

A 90% 10%

B 80% 20%

C 75% 25%

D 65% 35%

when I draw a pivot chart from it

pivot chart product column chart shows all SLA %age

like

90%

20%

75%

65%


don't known why it picks 20% for B when the pivot table cell clearly says 80% , and that's the only
wrong cell it picked all the other are okay. I am really confused with this.
