BPC RTC 10.1 Embedded, on S/4HANA, Model is not Validating

Hi Experts!
I am using BPC RTC 10.1 on S/4HANA 1610.

I would greatly appreciate if you can help with my last step of the following blog:

BPC Real-Time Consolidation (RTC) Initial setup:

https://blogs.sap.com/2018/06/25/bpc-real-time-consolidation-rtc-initial-setup/

I am implementing BPC RTC Embedded 10.1 consolidation. I followed all the steps from the blog and it works till I got to step 9 of the Advanced Settings. All my models mappings are working (have green check marks).

In the article, Advanced Settings section, Step 9 – Create the BPC Consolidation Model (4th diagram) shows blank, which is where I am unable to select (i.e., greyed out) for the following two Compounding members:

0FISCVARNT
/ERP/CHRTACCT

Also, I am unable to select under ‘Non-Interco member in Ownership’:
/ERP/ICOMP

However, in your Step 9 – Create the BPC Consolidation Model (5th diagram) shows values have been updated.

However, in my case, system will not allow me to update the two compounding members.

Any suggestion for a solution?

Your prompt help will be greatly appreciated.
