Composite Models - Visual break in PBI service

Hi,
In my dataset, I am using 3 tables from 3 different connections:
1. Oracle using import mode
2. Excel from Local disk

3. Existing dataset (Live connection/shared dataset)

(Note:
No relationship between tables. And no combination of data from multiple tables in a visual.)

For each source I am creating a visual separately. In a visual there is no combination of data from 2 different data source. 

In desktop all visuals are looking good. If I publish it to PBI Service, the visuals that contains data from existing dataset getting break and getting the following error.

Please advice, is this a known issue or am I missing something.
