Gradients with transparency effects not displaying when exported

The image on the left has 2 panels of gradient with a multiply effect in InDesign the image on the right is how it exports to PDF.

I’ve had this issue constantly for weeks, along with other issues that Adobe just won’t fix it’s getting to be a nightmare to use this crappy software.

I’ve tried every different PDF export option and compatibility setting there is it doesn’t help. With the exception that sometimes but not always, interactive PDF rarely fixes the issue.

I’ve changed the colour profiles too but doesn’t help.

It’s to the point where I can’t work using CC so will need to change my whole company over to Affinity if they don’t start fixing some of these bugs.

I’m still having this issue here that Adobe can’t fix, not sure it they are related.
