OCS OAI-PMH interface shows rejected articles

Hi,

I was playing around with some OCS OAI-PMH interface and noticed some papers appear more than once on the metadata list

for example, the paper ‘AÇÕES DE MEDIAÇÃO DE LEITURA E FORMAÇÃO DO PROFISSIONAL BIBLIOTECÁRIO’ is listed three times here

https://conferencias.ufsc.br/index.php/enancib/2019/oai?verb=ListRecords&metadataPrefix=oai_dc&set=enancib:2019:GT%206

or here,

http://www.ufpb.br/evento/index.php/enancib2016/enancib2016/oai?verb=ListRecords&metadataPrefix=oai_dc&set=enancib2016:enancib2016:GT%206

where paper

ANÁLISE DO MERCADO DE TRABALHO COMO ESTRATÉGIA PARA A MEDIAÇÃO DA FORMAÇÃO DO BIBLIOTECÁRIO: O CASO DOS EGRESSOS DO CURSO DE GRADUAÇÃO EM BIBLIOTECONOMIA DA UNIVERSIDADE FEDERAL DO RIO GRANDE DO NORTE

is listed 3 times…

also, rejected papers are listed, as in

https://conferencias.ufsc.br/index.php/enancib/2019/oai?verb=ListRecords&metadataPrefix=oai_dc&set=enancib:2019:GT%208

where the paper “JUPYTER NOTEBOOK FERRAMENTA PARA NARRATIVAS COMPUTACIONAIS” was not accepted, is not listed on presentations list, but is shown on OAI metadata

I know OCS is kind of locked in the past, but this seems to be something linked to a common lib also used in OJS and thats a thing…
