Dwg to pdf Mtext mask black boxes

Recently it was suggested that we should use The built in pdf maker "dwg to pdf.pc3" to avoid black boxes being printed from wipeouts.

That works great.

However when I created pdf's for several sheets, One of them (see attached) created black boxs from the mtext mask which was on and matched background but the wipeouts where ok.

And the strange thing is it didn't do that on all sheets. Is it the mtext setup on that sheet that cause the problem?

Thanks in advance for your support
