I would exclude this format/plugin from oai2 in:

https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Feprints%2Feprints%2Fblob%2F3.3%2Fcgi%2Foai2%23L559&data=01%7C01%7Ceprints-tech%40ecs.soton.ac.uk%7Cbf4319bea44c499bca5e08d81364c1dc%7C4a5378f929f44d3ebe89669d03ada9d8%7C0&sdata=vuiqX0tBj5RP6i0fhVDlybI2EhuwfHLvGHggnIQLHb0%3D&reserved=0

or you can change sort here (weak):

https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Feprints%2Feprints%2Fblob%2F3.3%2Fcgi%2Foai2%23L565&data=01%7C01%7Ceprints-tech%40ecs.soton.ac.uk%7Cbf4319bea44c499bca5e08d81364c1dc%7C4a5378f929f44d3ebe89669d03ada9d8%7C0&sdata=ySdc2CH1zcxEywn6m12iyC319ttNY%2FlAGNnXAlBfgvc%3D&reserved=0

I think this is an issue in DSpace, it should use always oai_dc as 
default format (instead of checking schema, the OAI specs cite oai_dc).
