issue with pagination and multiple checkbox selection (primeng)

I have a table with pagination enabled and i'm using 'p-tableHeaderCheckbox' to select check boxes in all rows

if my 'rowsPerPageOptions' is set to 50 and I checkec my 'p-tableHeaderCheckbox' all the rows will get selected(row from 50-100 also get selected)

Now It should selcet only first 50 rows instead 50 to 100 and so on....
