Manually added files marked as view by default

I have edited my Advancedsettings.xml and my Playercorefactory.xml files to have a manga (.cbr/cbz) collection detected in a library as videos files.
But all the folders and files are marked as view :

watch gallery


There is no option to unmark as read.
I’m on Kodi Krypton 17.1, using the Titan 3.7.56 skin (I was on Nebula before and had the same problem).

The advancedsettings.xml file :

Code:
<advancedsettings>
     <splash>false</splash>
     <videoextensions>
    <add>.wma|.mp3|.pdf|.epub|.gp3|.gp4|.gp5|.url|.cbr|.cbz|.txt|.rtf|.lit</add>
    </videoextensions>
    </advancedsettings>

The Playercorefactory.xml file :

Code:
<playercorefactory>
      <players>
         <player name="PDF" type="ExternalPlayer" audio="false" video="true">
         <filename>C:\Program Files (x86)\Foxit Reader\FoxitReader.exe</filename>

I’ve tried looking on the forum and on Google, but I’m not sure how put a name on this problem. I also hope that this thread is on the right place.
Sorry for the bad english.
