Indesign 19.01 PDF Export issue

[truechoicepack]

I recently updated my Indesign to 19.01, and I am having a slew of problems.  This exporting problem is the biggest one.

I am working on a document that looks like this

however, whenever I export it to PDF and take it to my local print house, he prints it like this.

I've been able to at least recreate the problem when I export to pdf/x-1a:2001 ( I typically use "None"), however, I have no clue how to fix the document so the printer sees and can print it right.

Does anyone have any suggestions?  I am at my wits end.

What platform?

If Mac and Sonoma - then InDesign isn't fully compatible:

Otherwise try to use PDF/X-4:

+1 for @Robert at ID-Tasker's suggestion to use PDF/X-4, which has been definitions for handling knockouts, which is what is happening in your sample.

It also could be how your printer's prepress proccessing software is handling the overlapped stacked elements, too.

FYI, PDF/x-1a 2001 is 22 years old, and a lot has changed with prepress during the past 2 decades.
