How remove Spell Slot?

I have a little problem. Modifying a player's token I multiclassed it and then removed it but in the Spell Slot tab in Action it has not been reduced. How can I modify it?

Thanks

PD: Sorry for the english but i am using google translator




Sorry I find. Is possible delete this post?

Sorry, no way to delete posts.

For those who come later, changing the class level does not add or remove class features. Drag and Drop will add levels and class features, but there is currently no similar method for removing class levels. You will need to adjust spell slots and remove abilities/changes manually. The 5E Character Wizard is in development and intends to add that capability in the future.
