Why do two charts (Table and Bar Chart) display different data?

Question

I have a strange issue in Google Data Studio where stacked column/bar charts are not displaying data correctly. I'm not sure if it's the way I'm setting it up or a bug. I've linked the Google Sheet and data page below.

Data Set (Google Sheets):

Date	Roll	Roller
1/4/2022	12	Oscar
1/5/2022	11	Oscar
1/6/2022	10	Oscar
1/7/2022	3	Oscar
1/8/2022	1	Oscar
1/9/2022	5	Oscar
1/10/2022	18	Dusty
1/11/2022	14	Oscar
1/12/2022	14	Oscar
1/13/2022	14	Oscar
1/14/2022	3	Dusty
1/15/2022	2	Dusty
1/16/2022	14	Oscar
1/17/2022	14	Chris
1/18/2022	8	Oscar
1/19/2022	9	Oscar
1/20/2022	14	Oscar
1/21/2022	7	Chris
1/22/2022	10	Alex

Google Data Studio Report

As seen "Chris" has two Roll inputs (14 and 7) on the table but in the graph it's only showing one:

Answer 1

In a Bar Chart, the default number of "Series" (unique values in the Breakdown Dimension field, in this case, the field titled Roll) is set to 10 and can be changed from the Style tab (with the current maximum of 20, which will be sufficient in this scenario as the Roll field has a COUNT_DISTINCT value of 12).
