Tried with +15 & after save it shows 15 only. Is it taking +15 as 15?
Tried with +5 & it changes back to 10. seems minimum value is 10. is it?
Currently it doesn't accept character "+". I can't save neither +15 nor +5. But 15 and 5 are saved without problem.
Yes, +15 is displayed as 15. I will try to change display format, +15 looks better
