Please help me i am so confused

i am brand new to all of this. im using the kiri moto web browser on an acer chromebook. im trying to add supports to my model. i go to the right and click on support and all it says is enable, all the videos ive seen show several other support options but i dont have those. when i enable and slice it doesn’t create an upward support but create like a flat pad leaving the model floating. using 3.9 version. im so confused. any help would be appreciated. thank you.

If you go to the top right corner and export your workspace with model that might help. Then people can see what you are looking at - or include some screen shots.
