PowerAPPS integeration with PowerBI ISSUES! URGENT , PLEASE HELP!!

Hello everyone, can someone help me?

I have integerated a powerapp in my PowerBI report to take comments based on the entry clicked by the user( there are 2 users( Planner and Supplier ) each User has a different powerapp Which opens based on the their specific button and some of the columns are fetched from the entry selected and user just have to write the comment eg; this item is needed etc and its saved in a sharepoint list.

I have 3 tables (2 of them sharepoint list) 1 is the main data coming from snowflake.

I am using patch function to patch the data from entry selected and save it in the sharepoint list.

I have imported the comment columns from Planner and supplier sharepoint list to the main table in PowerBI dashboard.

The issue is once i select entry which has no comment before( eg; no comment on either planner or supplier column before)

The powerapp shows bank screen and the comment column text input. But it should also show the entry selelected 4 columns which i imported in the gallery of powerapps plus i linked these columns also when i created the powerapp. But when i click on an entry which already has a comment it shows the info of the entry selected column.

Have someone experienced something similar or can help?

I would be grateful for any tips/help!
