Change professions in AMR

Hiya Mr Robot

I would like to temporarily change a profession on a trial basis in AMR, not in the game, I found a place on my character page were I can do this but it’s not sticky. I select alchemy in place of mining and click save.Then I return to the character page and I am still a miner. Seems like a possible bug (or a cockpit error:). Please advise. TIA.
