Looker drill-to fields with conditional formatting

[Kristjan]

How to remove the default "Show all 0" option from drill-to options and make sure that a link gives correct options when exploring?

Context:
Followed the steps described by (https://www.googlecloudcommunity.com/gc/Exploring-Curating-Data/How-to-get-visualization-configurati...) to get custom formatting for a drill to table.
2 problems with this solution: There is "Show all 0" now displayed that still shows the incorrect formatting for the data. The "explore" from the new link drill-to table will direct you to explore with incorrect options. 
How to get rid of the default "Show all 0" explore option and how to make sure that the explore from the link drill to table points to look with the same visualisation options?
