Update Fails syncing help database

While updating ERPNext: v10.1.43 (master), Frappe Framework: v10.1.42 (master). Backup was made before update, will restoring it correct the following?

Restore would just restore your working copy but if you update again you are likely to hit the same issue unless a fix is made upstream if necessary, or you can fix the problem yourself.

I decided to try and migrate to a new vm,

downloaded ova, imported to Virtualbox,
updated bench
drop site site1.local
install-app erpnext
copied sites/erpnext.vm from old host to new
restored database
bench migrate
bench setup production frappe

Now bench update works as expected, however when I try and raise a new Sales Invoice, I have patient and restaraunt table fields. Tried removing Hospitality and Healthcare from Domain Settings , without any effect. Is there a way to remove those modules? Or should I retrace my steps and change the migration ? I would also like to be able to create new Production Orders.
