Description with capital letters ignored in IBP excel

[christianhjerp]

Came across a really strange issue. Updating the Product Description in master data, but it´s ignored in the planning view. 
4 examples and only the first, highlighted doesn´t work. If the first word in the description is all capital letters it´s ignored. But adding X or even a space it´s displayed correctly in the planning view.  

This is regardless of excel version, we tried with 2308, 2311 and 2402. 
Versions are not active in this PA.

Please be careful with mixed case. You might not see what you expect if you filter by the description with mixed case or you use it update values without other attributes that make it unique. When I filter in IBP data view, I don't get back both spellings. When I display keyfigure, with just the mixed case attribute and no filters, I get two rows with values.

Reply from SAP, that this is coming from the 2402 upgrade. 
Even if the Product ID is the only key attribute, product description is impacted. 
So this won´t work: 
Product ID               Description
A123                        LARGE
B123                        large

The description will not display correctly.

Did you get any solution on this from SAP as we are facing same challenge?

No other solution than described above.
Even if the description is not a key. Below won´t work:
Product ID               Description
A123                        LARGE
B123                        large
