How can I update "slider revolution" which is included in aki theme?

Under plugins I can see just:

Activate Slider Revolution for Premium Benefits (e.g. Live Updates).
A new version of Slider Revolution is available.

I want to update becouse I have an error under "Query Monitor" - PHP errors

Warning"continue 2" targeting switch is equivalent to "break 2". Did you mean to use "continue 3"?1
