Tube fillet bead

Hi guys!

I'm in trouble. I need to put a fillet bead at two tubes. First I make the two tubes perpendicular, and when I put the fillet bead I get it.

But when I construct two tubes in angle the Solid Works show me an error.

I already tried to reduce and increase the fillet bead, but still show this error.

Can anyone help me ?

Thank you!

Márcio.
