How to bake smoke/fluid sims in 2.83

Can somebody please explain how we now bake a smoke sim in 2.83? As you can see at the bottom of the image below , the cache details and start/end frames are there but I can’t find a bake button to actually bake the sim. If I go to the cache folder there is nothing in it. In this thread here : https://blender.stackexchange.com/questions/167956/smoke-simulation-bake-is-missing-or-moved-from-2-8-0-to-2-8-2 somebody was having the same issue with 2.82  and the answer was apparently in the settings dropdown (red question mark in my photo)but it seems to have moved again in 2.83….  but as you can see there is nothing about baking. I am lost….. 

Thanks for any advice in advance 😁
