Load table from Dataverse and Countrow is different

Hi all,

i`m a newbie and i`m trying to get my first report done. So i loaded a table from Dataverse with a date filter:

( Table.SelectRows(dbo_myTable, each Date.Year([myTable_datum]) > 2021)

i tried also with a datetime function:

Table.SelectRows(myTable, each [datum] > #datetime(2021, 12, 31, 0, 0, 0).

When i click on save and take over, i can see that PowerBi (or the Power Query) is loading around 46200 rows.

I added a card with a measure:

(# Count rows myTable = COUNT(myTable[Datum]) or i tried also with Countrows(myTable) ),

but this card shows me only 35540 rows.
