Default format in move/cut cells

I use a custom template in Calc, with a font in all cells, but when I move a cell group ir leaves the old positions with another default format (font, size). Where can I chance that default?

This sounds like you did not change cell style Default (View -> Styles Manager or F11 and icon Cell Styles leftmost) but selected all cells and defined a new font default through Format -> Cells (or the equivalent right click action) when defining your template. True?
