Buttons Save and Back , Save , Cancel not appear for ESS Personal Profile

Dear experts

I have add the infotype 0022 using the steps of the following

Adding any Info Type IN ESS in EHP5/6 through WebDynpro Configuration

However when try of Edit the data the system not show the Buttons Save and Back , Save , Cancel as appear with other Infotypes(Address, Family members, persona data)

And only appear the screen without this buttons for save the information.

What is the cause of this issue?

This is the configuration V_T7XSSPERSUBTYP

Employee Self-Service (Web Dynpro ABAP)-->Service-Specific Settings-->Personal Information-->Personal Profile-->Determine Active Subtypes and Make Settings

My problem is because if I change a data, I dont can save this change . The system not show this buttons

Regards

Thanks
