When saving a set of parameters as an export preset, you click the '+' button and then nothing happens. What you need to do is navigate away using a different tool, then navigate back to the export for web dialog to see your new preset appear. Its an odd behaviour that doesn't seem like its supposed to work that way.
Also the export for web presets do not appear like they do in the promotional tutorials:

Hey there, in a previous update, we moved the presets from the presets bar as we plan to eventually remove it for all tools — it takes away a little too much space from the canvas so we want to move everything to the Tool Options bar. The screenshots on our website are all up to date but it's a little more tricky to refilm all the videos.
However, when you click the + button the preset should immediately be added and the name should become active so you can rename it. Here's a screenshot of what that looks like:
Is this not what you see?
