Half of my drawing missing in flat pattern

Hi everyone,

I recently started working with solidworks. Usually it seems im doing fine, but this time i really hit a brick wall.

After i added the beadwelds, i safed the document, then later i wanted to check my flat pattern to make sure it can be made.

To my surprise; half of it is missing. It seems to be the first half of the sketched bent thats gone and i have no idea how to get it back.

I have added the file.

All help is welcome ! Tnx in advance !
