Clarity

I am having a strange problem in Clarity 13.3. I have created a grid portlet and adding some calculated attributes to this portlet. Some of the Calculated fields are coming up blank with no value in them. I have two of these portlets created for different objects one fields calculates properly on one portlet but shows up blank on the other. I tried deleting the attribute and re creating it and in some instances this worked, but I other instances it didn't. Not sure what could be causing the issue. Anyone have this issue before. See a pic of the sample portlet attached.

I opened up a case with CA and I am placing the resolution to this issue below. This was happening to me in 13.3.

Resolution:

CLRT-71923 - Sum of calculated numbers fails when attribute id of the sum includes an underscore This couldn't be
reproduced in version 14.1. Workaround: Do not include underscore in the attribute id of calculated attributes.
