Can not find SQLite component in ongoing project but a new project has

Dears, I worked on an importd aia file for many days alredy, it has SQLite extension, but, in palette of “storage”, I can not find SQLite like bellow picture shown.

but, when I created a new project, the palette inside “storage” has this SQLite model ( show in bellow picture). why? I need to use this official SQLite instead of the extension. because they have differient blocks.

I have ever deleted the SQLite extension, it didn’t work.

Do you main when you used an SQLite extension ,SQLite component of Kodular hidden ?
And what is extension you are used ?
