Issues with character tokens on maps

[rtrm]

So we are converting our Dungeon of the Mad Mage campaign to FGU. We have had a couple of issues with maps and characters, the main one being that players are unable to move their characters through 5' doors (I'm using the Level-9-Players map). Players can't drag their characters through 5' doors, nor can they use the cursor keys to move through them. It seems to be an issue with the doorways being in the middle of the corridor. I think it's a problem for other doorways, but the specific one we've come across the issue with is the one leading into area 09.42.42.

Players also have an issue with the map going blank when they move their character until they click on their character again.

Finally, I've found that sometimes I, as the DM, can't select characters on the map, closing the map and re-opening fixes that issue.

Yes, I have seen on rare occasions where a token refuses to go through a door when there is a grid line bisecting the door space. The DM can move the token for the players though so it''s not a big issue since its rare.

Unless the player has their token selected the map will be black. Haven't come across any issue with the DM not being able to select a token. Are you using any extensions? or do you have multiple themes loaded?
