Caption in screens designed from scratch

Hello, in the screens designed from scratch when I change the title that has to leave the tab (caption) in one of them, if I accept and repeat the operation with another screen and put a different caption does not keep it, it still has the caption From the previous screen. What can be my mistake?
Thanks and regards.

Hi,

Probably you create screens in the same package, so they have a common messages.properties file. The message key is also the same so the screens share the same caption.

Sorry Konstantin but I do not understand, should I create a different package for each screen you create ?, attached screenshot, below the screen item is where I create all my own screens, what should I change here so that each one has its own caption? .
Thanks and regards.

You can either create screens in separate packages or use different keys for screen captions (it is caption by default) - see Caption field on the screen properties tab.

Thanks Konstantin, it has become clear to me
