Promoting reports from Test to Production not finding right dataflow

For one of the 2 reports we have seen the issue for, we did have to remove the report and dataset in test, because the Exploratory/Dev -> Test deployment was also not going through properly. As a result when deployed to production it was coming through as a new report which makes sense. The test deployment was finding the test dataflow though, but the production deployment didnt find the production dataflow.

For the second we had no issues deploying to Test, but still when deploy to production (overwriting the previous version), it remained connected to the test dataflows rather than production.

The dataflows havent been removed at any point
