Labels Showing Wherever They Want When Form Is Maximized?

I have a form showing a datagrid with info from a database. It also has 2 date pickers to filter the database results. It shows everything perfectly in the datagrid, so the db connection is ok. But it also has a few labels below, showing some info taken from the datagrid. For example, the datagrid has sales information and the labels below show the total sales. This works fine too.But the problem comes when I open some other form, maximize it and then open this form containing all this stuff (while the previous one is still open and maximized). These labels (along with a few more labels that only contain the '$' character) get on top
of the datagrid. Even if I restore the form to its normal size the labels are positioned wherever they want. The weird thing is that this only happens with some labels and not with all of them.My first guess was the anchor property, but I set it to left-bottom and it still does this.
