OpenGround Excel Extension Multiple Charts

Is it still possible to have multiple charts on one sheet?

When I try to create more than 1 chart, the Charts info screen assigns everything to "Chart1" and does not allow it to be changed. When I GENERATE, it reassigns information from the 2nd chart to Chart1.

What is the workflow for having more than 1 chart?

The graphs below should show Blow counts and N160 on the left and Factor of safety at depth on the right
