Duplicate app and new database ... but old data ???

[andreagiordano]

I duplicated my app to do some tests and changes. I created a new database form the older one with a different name. Strangely enough if in the Table and chose View Source it shows me the correct file (an empty file, only headers are left). But if I chose View data it shows me the old data and even in the preview of the app old data are shown ... even after various refresh and syncronize.

 former app. I can't see this folder in my Drive

new app's folder I can find it but anyway is empty

Strangely enough the number 2177.... it's the same for the two apps. The version number of the app instead is very different 1.000500 and 1.000019 for the new app. 

And yet two are the apps:

Where or what should I check?

Thanks
