Can't Set Images to "Unidentified"
I noticed when sharing an image from a monster I can no longer hide the image name by typing in a name and then setting the image to Unidentified. This means the players will see the name of the image - or monster name when I don't want them to or when I want to use a different name.
I noticed two different behaviours between the WotC's Monster Manual and Kobold Press' Creature Codex.
I checked using an Adult Black Dragon out of the Monster Manual. In the monster manual first select the Adult Black Dragon and get the NPC popup, select the Notes Tab and click the image link. If you unlock the image you can put something (ie Big Dragon) in the unidentified box but there is no way to set the image as "unidentified" so the player will see the unidentified name "Black Dragon" instead of the name of the image from the monster manual.
In the Creasure Codex when select an Acid Ant npc and click the Notes Tab and click the Image Link. When you unlock this image there isn't even an "unidentified" text box at the top.
The same appears to be true for map images as well though them are like the monster manual where there is a text box for the unidentified name but no way of setting the image to be "Unidentified".
