Issue/Introduction

Issue Description: STDOUT logs will also be contained when downloading/filtering the STDERR log in App Metrics.

How to reproduce?

1 - Select the following filters and click on APPLY button:

• APP (Application)
• STDERR

2 - Confirm that only the STDERR log line was displayed. This is working as expected. 

3 - Then click on DOWNLOAD button with the same filters being selected to export the logs. Only STDERR log lines are expected to be exported to the file.

4 - However, it is confirmed that both STDOUT and STDERR logs are being exported to the file.
