Nice being part of the forum - I'm a Jamovi beginner who is learning to love the software more and more for every day

A couple of questions if you don't mind.
1) I'm analyzing an A/B test data set found here - https://www.kaggle.com/zhangluyuan/ab-testing
Now I have filtered out problematic instances where the control group has been assigned the new page (which they shouldn't).
(https://monosnap.com/file/8eDQMPN8cy6Op ... YWH68ZnzM8)
Now I want to drop those rows from the data set but I can't figure out how. Also, I would very much like to understand how I can sort by column, i.e. change the order of sorting (from for example ascending to descending).
2) Is it possible to do a Proportion Test (2 Outcomes) in Jamovi?
Thank you very much in advance!
