Missing centre line in drafting

[Nikola_Kolev]

Hello from Bulgaria,

I had modified one solid ( plate from injection mold) and when I returned to drawing to make modification in dimensions I saw that some centre line are missing. 

I did not modify this part from solid where lines are lost.

Some advise ?
