Thank you, Rahul, for your comments. I now understand what the issue is.
The first problem is fixed but the second is not for sure.

I just created a ticket on JIRA. I am hoping this will be fixed sometime
soon because I am working on my customer's data with a data analytics

How long should I expect this to be solved? Does anyone have clues on how
long I am supposed to wait for the bug to be fixed?

Thank you,
