SECTION LINES PROBLEMS

Hi,

I am getting crazy with the section lines in drawing.

I have a few broken views (the part is so long),  every time I put a section line the line itself disappear and the other attributes are impossible to edit.

I can see 2 segment of the section line out of the sheet title.

Is there a way to overcome these problems?

Please help

P.S.

I am using Solidworks 2016 SP4
