Hello,
We have test on your website, and reproduce your configuration on our localhost, and on our side it work as expected.
Meaning, that from your configuration the shipping method that cost 4.90 Euro shouldn't be displayed.,
And given your settings if the total of the basket is greater than 50 Euro that isn't possible...
So, can you provide these elements in order to better understand the context :
- Url link to administrator access
- Backend user with maximum Acl
Awaiting your elements to progress on your subject.
Regards
