Description Line 2 on F4311

Hi All ,

I am logging this for a colleague of mine so some of this may be 'lost in translation', anyway to make a long story short , when doing 'Direct Voucher Match'  the application allows you to change / Add fields such as Description1 and Description2. My colleague changed one of these during the process and didn't receive any errors to say she couldn't do this , but when inquiring on the files afterwards none of the details have taken , so should this update , making this a bug or if not why does it allow you to enter into the box?

I have attached a screen shot which shows what I mean
