Hi, 

On odoo V11, I modified "new repair order" template of the "repair" app with toggle studio and close.

I have deleted "product to repair" field and also wanted to delete "quantity" and "unit of measure".

When clicking on quantity field in toggle studio, I realized that quantities and uom are in one technical settings/manage multiple units of measures field. 

Clicked on remove form view and closed.

When tried to open a new repair order, I now get this error

Error:

Uncaught Error: Unknown field invoice_method in domain

How can I repair this problem?

Or how can I reset repair module so that I can start again from scratch?
