archicad 13 - problems displaying layers and quotas

[contursi]

Hello.
work with archicad 13 to a file that in the meantime due to the various sections, plants and layouts became very heavy (about 20 mb).

today I opened the file and suddenly noticed strange phenomena.
every time I plan, all layers are automatically switched off.
Besides, all odds are gone!

What's going on? Can't I understand? and maybe a file bug?
I'm desperate, because I have to finish the job by tomorrow.

but climb a floor using the appropriate command (or the shortcut shift + f2), or to climb clicks on the top floor view saved in the view map?
