Getting two dots, on export into EPS file

Hello,

it's me; the new Kid on the block.   ;-)

Sorry for my stupid questions...

Till today I was working with Designer 7 and had to change to Designer 12. 

Most of the usage is still the same; but different.

Normally I make 'n export into EPS

My file is (e.g.) called: 52b1001aa.des

but on the export, the name is changed into: 52b1001aa..eps

I expected to become the file-name: 52b1001aa.eps

I have no time, to edit the file-name; always. 

Is there any solution?
