plus zeros

Hello,

It's a problem i've just found and the first time i've met, In the chart of my report and in dashbord, all the data in format % had a leading zero in plus

this is a chart in a report

And this is from my dashbord

But they were all good in my desktop report without leading zero.

And i try to refresh or re-update my report, none of them works.

Anyone has a idea of this problem?Is this some mistake i've made in my report, or just a error?

Thanks in advance!
