Bug new threadlog features throwing errors on certain accounts

Going to my threadlog from https://wolf-rpg.com/misc.php?action=threadlog

If I have selected a trade for a thread I cannot change it back to "No Trade." I can change it to any other trade, but it won't let me remove it back to default. This is the case with the thread active and after being archived.

If reaching the log from my character menu: https://wolf-rpg.com/misc.php?action=threadlog&uid=7775
The dropdowns are there, but there's no update button present at all


In both cases, even though I've toggled "Yes" to exiting a thread (the howl one with lots of users) - at first it removed it from my "need replies" count correctly, but for a while now it says I owe a reply again. Toggling yes/no and updating doesn't fix this.
