I'm facing an issue while trying to create collections from a list comprising approximately 9500 items (ID 11,000-20,000). My aim is to create a collection at the app OnStart I'm using the following process to create different collections and then consolidate them into one:

Concurrent(
 ClearCollect(
 colNotesA,
 Filter(
 'Social Services Notes',
 ID < 13000
 )
 ),
 ClearCollect(
 colNotesB,
 Filter(
 'Social Services Notes',
 ID >= 13000 And ID < 15000
 )
 ),
 ClearCollect(
 colNotesC,
 Filter(
 'Social Services Notes',
 ID >= 15000 And ID < 17000
 )
 ),
 ClearCollect(
 colNotesD,
 Filter(
 'Social Services Notes',
 ID >= 17000 And ID < 19000
 )
 ),
 ClearCollect(
 colNotesE,
 Filter(
 'Social Services Notes',
 ID >= 19000 And ID < 21000
 )
 )
);

ClearCollect(
 colSocialServicesNotes,
 colNotesA, colNotesB, colNotesC, colNotesD, colNotesE
);

However, I've noticed that the number of items returned in each collection doesn't add up to the total of over 9500 items that are supposed to be in my list.
