Seven ult wrong icon

[Igobee]

When hovering over seven ult the number of charges icon (electric bolt) is used for duration, instead of the normal duration icon (hourglass).

This is what it should look like on an ability with all correct icons:

That bolt icon is also used for channeled abilities (time when you are not able to provide any action), so I'm not sure if it's really a bug, but it's definitely confusing to newbies

I don't think the same stat having two different icons is intentional, but they really should have a legend for these icons somewhere it was beyond confusing when i first started playing.
