Deleting row in matrix.

Hello.

I have weird problem.

If I add some rows to matrix, and then delete rows the method with:

m_pMatrix->GetRowCount();

return the number of rows without delete.

For example:

If i have matrix with 5 rows, and I delete 2 rows, method with GetRowCount show me 5 😔

What is wrong ?

I solved this problem with adding new variable, but why does it work wrong ?

Sorry for my english.

Regards
