Couldn't set formatting and style in Bar options

In Metabase 0.46.1 Bar options, if using the Sum Metrics or Custom Expression, I couldn't set the Formatting and Style. Because the entrance button is missing.

hmmmm I am not able to replicate that

Can you share what custom expression you are specifying please and how the GUI question is setup

I just found the reason: the column I used in sum function is category type. After I change it to quantity type, it works. I could change the format and the style. But I don't know why category type could use sum, but couldn't change the style and format. I need to change the name and color.

Thanks for this! Opened a bug, for reference Column set as category allows numeric aggreagations but not Styling and Formatting · Issue #30431 · metabase/metabase · GitHub
