Dataflow doesn't load a table

I have a dataflow with several tables. One of my reports is based on this dataflow and it used to work well until last week : one of the table is not loaded anymore.

1/ When I open the pbix file and try to transform data : the table "Plants" appears with an error : 

2/ When I click edit settings, i see this : 

3/ Then, I have a look at the dataflow. I find that the table is empty 

4/ But when I click Edit Tables, I can see data in the Power Query editor :

I don't understand why I can see data in stage 4/ but the table is empty in stage 3/.

Additional information :

- I directly queried the Oracle database to make sure the table actually contains data.

- The dataflow is refreshed daily.

I am not able to solve it by myself so far, help will be appreciated

Best regards,
