Unmanaged devices auto-removal?

[Ufoto 14]

Hello,

We have a ESET Protect Cloud which is synchronized with AD using AD connector. Initially the connector imported all computer objects as unmanaged devices which is what we expected. However now that we started to deploy the ESET Agent we noticed that the unmanaged entries are not disappearing when a computer becomes managed. Instead there are two entries for such devices - managed and unmanaged one. 

Could you let me know if this is the expected outcome? Should we manually delete the unmanaged entries once systems are provisioned? I expected the entry to be merged as it shares the same hostname and LDAP location. 

Thank you in advance!
