Persistent Data Warning in dual sim XZ

[xznewbie]

Hello guy,
Recently I was getting a nagging triangular symbol with exclamation mark inside, stating my excess data usage. How can I remove this. I already reset the date as well as the desired data usage according to my prepaid data plan which is different between the two SIM.
However the old number is still retained and not removed.resulting in persistent data warning usage symbol at the upper left side of the screen.
This used to be not a problem with my old Xperia Z as the moment I reset to a new plan the old numbers just vanish
Can somebody help me sort this out..?

did you try to disable set data limit and restart your device?

does this happen on safe mode?
