had a similar problem and I could solve it by eliminating
the QWeb Template from
Settings --> Technical --> User Interface --> Views.
Then, you need to update the module.
I hope I've helped :)
update
ir_model_data
set
noupdate = false
where
id in(
select
model_data_id
from
ir_ui_view
where
name = '<the name of your template - in my case tpl-imprint>'
);
