Electrode issues

This is my first attempt to create electrodes, and i have some questions/issues.
i want 2 electrodes for the same feature, but with different reduction/gap. Do i need to create 2 electrodes to do that. Under electrode blank you can set gap/quantitym but that doesn’t seem to do anything.
I also tried to export the electrode but i can’t select the electrode. My intention was to set the gap under the electrode and export it to a new file, and end up with a file for each electrode.
The last problem is that the electrode is missing a face at the end. Is that because the electrode goes partly down into a hole. I fixed it with the fillgap command under heal.
I’m using zw3d 2020.
