Glue Job Studio - Output Schema - Edit and Apply does not save changes

Question

I have a glue job that is reading a couple of CSV files form S3.
1. I manually choose examples files to infer the schema, that works fine.
2. Then I add a join action but I don't want to infer the schema form the data preview session, so I manually Edit and Apply the schema, but my changes on the Schema are not saved.
3. This is causing the join action to not have any output
4. if I want to use that join action as input to another join I'm not able apply conditions base on the first join.
5. I'm not using any Catalog or database

All of this was working fine a couple of weeks ago, I'm not sure if an update on the Glue Studio can be causing the problem.

Any help is really apreciated, thank you!

Answer

I have reproduce that for the join field, will report it to the team.  
However, bear in mind that the schema is meant to reflect the data, not the other way around, if your schema doesn't match the preview then you need to do mapping/casting as required.
