Disable authority control on field

[Usv]

Hi,

In dspace 6.3 with Authority control and ORCID enabled on author field, I want to disable this 2 features as they are not working properly. (doubled entries in author browse list, key instead of author name, etc)

I commented  Authority and ORCID settings in dspace.cfg.

Reindex process dspace index-discovery throws the error: 

No choices plugin was configured for field dc.contributor.author

How can be bypassed this error? Or how to disable Authority control?

Thank you very much in advance
