I'm not completely sure why, but I think it will work
if you put Country / Segment on the tooltip
of the second axis (Container 8 and Container 10).
Not sure why the square would prevent the tooltip.
Please see workbook attached in the Forum Thread.

Thanks so much, you are right. I guess once size is increased to Max it must be like having 2 text boxes with one perfectly in-front of the other.
After seeing your post I tried the below, which also works.
- Right click on any column header and select "move marks to back"
Thanks again for your help
