I am trying to group this SSR report builder based on an old Crystal Report

Question

I am converting some old crystal reports to SSRS report builder version. There is just 1 query but when I try to add Groups in SSRS. It does not look right.. it expands to the right. In Crystal, this report is grouped by Region, OwnerID and TagNo. How do I achieve this in SSRS and would like it to be Grouped the same way as CrystalReports. I am new to SSRS. See Image below. Updated: Currently it is like this below. I add a group to the right like the Region, Owner no, tag no. I just want it to be Grouped like from Region first then Owner and then Tag no... these are based on Parameters on SSRS. The Crystal one works like this well but cannot figure out the SSRS version. The 2nd screenshot below has 2.. one using a list and the one slightly below is using a Matrix... either the list or the matrix is not showing like the one in Crystal. Thanks

Currently it is like this.
