Count of month, in the contract info after entering the end date, does not work

Hi everyone!

There is a problem with the count of the Initial duration in Contract Info. Specifically when we insert a date of more months.

When we enter the end date, which for our client is entered before the Initial duration of the contract, the default system calculates the duration in months. If I try to enter the value in days, it will automatically deletes the date entered and we can't calculates the date in days or years and so on, because every changes of the measurement unit delete the date we insert before and so we were always in a loop.
