Incorrect tooltip showing on analyse page

[chrisjwood16]

On analyse page - for example - https://openprescribing.net/analyse/#org=regional_team&orgIds=Y60&numIds=2&denom=nothing&selectedTab=summary

The show vs others tab has a toggle to switch between items and spend:

The time series tab does not have an items / spend toggle button and only shows items. But if the toggle is set to spend on the show vs others tab the tooltip erroneously states that it is showing spend (when it is actually showing items).
