After updating to the latest JO Update, 1.16.7, I no longer have the dropdown option in the Orders tab, “No& Code” column.
Running Windows 10 with Java 8 Update 181 (build 1.8.0_181-b13).
It was working fine until I ran the update to JO.
I uninstalled and installed JO 1.16.6 from the ME Games Website and had the same problem.
I went to the vault and then to the old JO Wiki site, https://github.com/JOverseer/joverseer/wiki , and found the 1.16.3 version and it does work. I am not sure what other issues it might have that the new versions were supposed to fix, but at least I have the drop down in my orders section now.
