Lightning counts shows a temperature when hovering over graphs

I am using the lates (April 24, 24) wd for windows (11) and plotting lightning counts from a tempest on the main graphs. When not hovering over a time the Lightning counts shows a number or zero, but if I move the cursor over say the highest spike - it shows something like 74 F

How can I fix this?

You might have to contact Brian direct :confused:
