Data Modeling: Relationship Error while fetching data from 3 tables

Hello Power BI Community,

I am trying to fetch data from three different tables which are connected in my Data Model but the relationship error gets thrown. The screenshot below explains the data points and how the tables are interconnected within my PBI File.

Now, if I bring Cust_Code from RLS Cust Details (Table A) in a table visual and Occupation_Name from Occupation table (Table B), nothing breaks and the information is shown correctly.
Similarly, if I bring Occupation_name from Occupation table (Table B) and Geo_ID from Occupation Geo Bridge table (Table C), it shows the information correctly. Attaching screenshots below for these two points:

But If I bring information from these 3 tables altogether i:e Cust_Code from Table A, Occupation_Name from Table B and Geo_ID from Table C, I get the error: Power BI can't determine the relationship between two or more fields.

Also, If I add a slicer to the report, and use Cust_Code from Table A to slice the information of Table B and Table C, that still works and slices the information correctly.

I am building the model from scratch and trying to understand the behaviour of relationships in this case to avoid any bottlenecks. Why am I being thrown with an error as shown in the screenshot, but at the same being able to slice the information for that particular table.

Also, for one of my other project files, the same functionality is applied and I am able to select the data from each table collectively in one table. Is there any particular concept which is involved here that I am not aware of.

Any help on this would be highly appreciated. Please let me know if more information is required from my end.

Thanks in advance.
