Manually added electrode not shown in MRI Viewer

Hello,

i manually added an electrode in the MRI viewer.
I can set the contact positions but the Electrode is not shown afterwards. I tried this with SEEG, ECOG and ECOG-mid and neither of them are shown after determining the positions of the tip/skull-entry or the corners of the grid, and choosing the right settings for width, height etc.
How can i display the Electrode?

Thanks for your help.
Best,
Nina
