CUstom Modules and Packages

People,

I would like to know if one of you have faced this kind of trouble

I have installed SuiteCRM Version 7.5.3 / Sugar Version 6.5.23 (Build 1061).
I am trying to create a new module, so I have to go to “Module Builder” and select to create a “New Package”.

That is a real mess, because after I fill the mandatory attributes (Package Name, Key) it does not Save.
Going back and forward in the application I made it and it save and created the package. Now, is turn to create a new module. Same problem with the Save
Finally, I loaded relationships, labels and fields, but now it does not accept Deploy, export or publish in order to test what I created and see how it works

Any idea??
