The dropdown for picking the name of the table is not working correctly and I will pass it along to the developers. The workaround is to do what you've already indicated and manually input the name of the Global Table using the Code Editor.

For the bigger issue, the problem is a timing issue with when the recipe table is updated internally in the FluidMixer. The problem is the FluidMixer has already set some data for the first step of a recipe by the time the OnEmpty trigger fires, so the next batch is using old data for its first step.

The solution is to either create a dummy Step 1 in the Mixer Steps, or send the message before the last step has finished its delay time. Both of these solutions are done in the Steps tab of the FluidMixer.

For the first solution, just add a dummy Step 1 in the Mixer Steps table with a Delay of 0. Then set up steps 1 through 4 as steps 2 through 5 instead. And in the Mixer Recipe table, add 1 to each ingredients Step column, so they use steps 2 through 4 instead.

The other solution would be to go into the Code Editor for the Before Step Delay trigger and add this code:

// If the delay for the last step is starting, send the message.
if (getvarnum(current, "curstep") == getvarnode(current, "currentsteptable").as(Table).numRows)
	sendmessage(current, current);

Be sure to add any parameters you want to use in the OnMessage trigger as part of the sendmessage() command. For instance, in your model you are sending a 1 as the first message parameter, so something similar would be:

sendmessage(current, current, 1);

You'll also want to remove the OnEmpty trigger so it doesn't send another message after the mixer is emptied.
