VLC Mobile Android Vers. 3.0.13 try to logs twice on Mediaserver - Default AND Guest User

Hallo VLC, so first sorry with my rosty english.... The scene is: Android 6-Smartphone (LG) IP-Adrs 192.168.104.22, Android 7-Tablett (Samsung) IP-Adrs 192.168.104.42, AVM FRITZ!Box 7490 with open NAS-Function (SMB), IP-Adrs 192.168.104.1 Default User: "FritzBox4" There is no user "guest" There is one internet filter profile "Gast" that is bloked to all except surfing and mailing App "VLC für Android". (all updates true)

All works fine BUT: While get connection throug VLC-App to Fritz!Box smb-service the router FRITZ!Box gives to (most more) following event-log entries "Anmeldung des Benutzers Guest am FRITZ!Box-SMB-Dienst von IP-Adresse 192.168.104.22 gescheitert (Benutzername oder Kennwort falsch)" english "login user Guest at FRITZ!Box-SMB-service from IP-Adress 192.168.10422 failed (Username or password wrong)" AND the follow entry "Anmeldung des Benutzers [Default] am FRITZ!Box SMB-Dienst von IP-Adresse 192.168.104.22." english: "Login user [Default] at FRITZ!Box SMB-service from IP-Adress 192.168.104.22" (means positiv login)

It seems that there are 4 or more twins with one action App-VLC, local network, networkfavorit "FB4 D24", directory "D24", There is no different betwenn playing music or video. Only look at an directory gives this those logentries.

For shure i re-installed VLC-Android - same bad eventlog. This procedure is reproduceable. So i am able to send you all needed log-files and screenshots, additionnaly if possible
