Sudden layer transparency

[Emanuela-NADA]

Hey guys, 

Super weird situation so hopefully someone knows whats going on.

When I started up Illustrator this morning and started my project I noticed that everything appears transparent, I'm able to noticebly see my underlying layers while everything is at %100 opacity.

I didn't change any settings or do an y updates since yesterday and haven't experienced this before this morning.

Thanks in advance.

Emanuela

There are some objects that show a filled dot at right side of the layer panel. that means they have a transparency setting.

Select them and check the Transparency or the Appearance panel.
