World name: Mateus
Character name: Kismet Kaze (Though it has happened on all characters with islands, and I had a friend test it on a different installation and it happened to them as well)
Class/Level: 90 any class
Party or solo: Solo
In-game time: ST: 9:44pm, ET: 7:00pm
Area and coordinates: Unnamed Island ( 12.9 , 28.8 )
Steps: I have not tested this on anything but the PC version, so I am unable to say if it's happening on a console.
  1. Talk to the Tactful Taskmaster and select "Review the workshop's agenda"
  2. In a workshop, click the "Set Agenda" button (the plus sign to add an item)
  3. Make sure your sorting is by time
  4. Put in any 4-hour workshop item
  5. Click the plus sign again
  6. Do not close the 4-hour item toggle. Instead, scroll down and open the 6-hour item toggle. Instead of "Imam Bayildi", you will see "Wooden Chair" and it will be highlighted. If you hover over it, it gives the tooltip for Imam Bayildi. The description will be for the wooden chair. If you just click the "Schedule" button (don't click the wooden chair's name on that list), it will schedule a Wooden Chair. HOWEVER, if you click the Wooden Chair, the name and description will change to Imam Bayildi, and you will be able to schedule it.

NOTE: This only seems to be happening when putting in a 4-hour item and then putting in a 6-hour item. It also only happens if you scroll down and click the 6-hour toggle without closing the 4-hour toggle. I'm unsure why this is happening. If you scroll up after the bug, and then scroll back down, it turns back to Imam Bayildi without clicking on the name.

See screenshots below:

After clicking on the name (or scrolling up so that it's hidden and scrolling back down):
