My collections are not cleared even after closing the app and the browser.

They retain all the columns but are empty (no records).

Your collection is cleared. The collections viewer is simply showing the column headings of what the empty collection looks like. This is a necessary feature because it allows us to validate the a collection holds no values.

The collection will continue to appear in the collections viewer so long as there is at least one reference to it in your code.

Thanks, but what is wrong with my app then? It consist of a single button, by pressing which I wan't to operate some SharePoint lists. Lets say I do:

Clear(z3);
ForAll(z1,Collect(counter,Last(counter).Value+1);
Collect(z3,{
SignalTypeId:Last(FirstN(z1,Last(counter).Value)).Value,
DatasetId:Last(FirstN(z2,Last(counter).Value)).Value
}));

ClearCollect(z1,AddColumns(z3,"SignalType",LookUp(SIGNAL_TYPES,SignalTypeId=z3[@SignalTypeId],SignalType)));
where SIGNAL_TYPES is a SharePoint list.
Last line gives me the error that SignalType already exists, although I just created z3 with only two columns SignalTypeId and DatasetId.

No clue. You should create a new post focusing on explaining the actual problem you are having rather than what you believe the solution to be.
