Surfacing a cut and filleting all around ?

Hi MoI friends,

I have some troubles I would like to understand... Well... In fact I have again some trouble to try to understand yet ! ;-)

A behavior I have difficulties is the fillet tool.
I understood all is not simple in fillets cases, but I would like to understand why my fillet at the bottom of my piece cannot be set wider than 0,82mm, and why at 0,82mm it does not end without a planar surface.
I would like to obtain a fillet all around my piece, as I have already rounded some edges as you can see.

The second issue I have is I cannot do a surface to end my elliptic cut, even if I make one closed object with the edges of this cut.
I have to obtain a fillet also for the edges of this cut. (say all the edges of the piece have to be rounded the same way)

Of course the first try I have done was to just select the whole piece and to make a fillet tool, but alas without any success.

In attachment there you will find a sample of my piece to see what can be happened, and I hope (in fact I'm sure ;) that you will be able to explain to me how I can do...

Cordially,
