Layers turned off in Xref, but still preview/plotting

I am trying to find the solution to a problem, I have worked for weeks on this.

I am working on a drawing, when I turn the certain Xref layer(s) off in model space, then I go to layout tab and try to print a pdf, the turned off layer(s) is showing in print preview. It also prints.

I have tried visretain, that's not it.

I have deleted layer states and have some success in the turned off layers not plotting, but this is not an option.

What am I missing?
