Fernando - I am not providing a solution here but I am sharing my experience where I had a similar problem sometime back. But I had this kind of issue with Combo & Block Chart. When I had copied the Combo Chart and tried to convert the same chart to combo... It was not showing the data for all the dimensions. Inspite of increasing the limit to show everything possible, it did not work. I had to recreate the chart again and it works as it should be...
I'll keep an eye on this post.
Cheers - DV
I had a problem like this before, but I was not just a version upgrade.
I had some dimensions that were renamed and then they were unavaillable that disabled sorting in the object
If I remember correctly, in some cases I had problems with disabled expressions as well... but I'm not sure...
