If you're talking about prepopulated salary amount in income tax website, then you should try filing freshly. I had a similar problem and it is working now.
And bug is there after fresh install without using previous json too. Tested on ITDe-Filing Setup 1.0.20_0, working in 1.0.12
Hard to believe that just 1 month from extended due date these guys have still not fixed issues.
Infosys/Tax dept testing really sucks if you can have such easy to reproduce bugs in stable version - a regression, as 2 months back it was fine.
Worst tax utility in last 10 years, i dont remember ever facing a bug in ITR forms - excel/java.
