Fix typo and tell_pbar

Changes proposed

Check if msg is empty or not before calling pbar_sender_pipe()

Typo in main screen "[Main] " overwrote the first few character("Total A"). Adding [Main] is a simple fix but not permenant. I believe more analysis is required to understanding the reason of overwriting. Also the whole statement is printed once after "Flow Processed" line, but then disappears. Careful observation is required to notice this.

@AlyaGomaa can you review my PR.

This CI-staging should not be failing based on my changes.

Seems like dataset-integration failure is common among PRs.
