Hey Alan,
Thanks for adding to sources to this profile. You are using a reference system with numbered sources and copying the IDs over as well. Most users of WikiTree associate that with 'imported gedcom' profiles.
Example: Source: S17 1841 UK Other Census June 6th 1841, TNA Ref: HO107/434/17/35
I personally would not use the numbering in this way. It is hard to keep those in line with the page layout. You can use <ref> tags aka inline references. Then the WikiTree system will create the correct numbers automatically. If you use a name for the source (<ref name="S17">...<ref>) you can reuse that reference as well (<ref name="something"/>).
This would require adding names to the already present references.

The Orphan Trail they offer is a great way to learn sourcing etc.
