Reconnect to the data source breaks every field

[Mathys_]

Hello everyone,

I am encountering what I think is at best a bug, at worst an badly handled scenario.
When trying to reconnect my data source it identifies every field as 'Missing field' and then as 'New field', you can see very clearly this on the screenshot. The data source is a Google Sheet with the basic google sheet connector.

On top of that, the database has not been much changed, the data types have not been changed and I have a second separate report that uses the exact same data source but does not show this issue when trying to reconnect.

Did anyone encounter this scenario and can help me with it ? My current stand is that it is coming from the Google Sheet document general settings that changed and creates a problem with the looker reconnect.
