Nevermind, I barely touched the station all these months so I didn't notice.
But after watching your picture I realized something... there was too much empty space between the tip label and the bar.
Then I remembered! I had tried even larger text, 13 or 10 chars, so
I had to reduce the power bar.
The system became unstable and crashed, so in the end I set it to 8 chars... but I forgot to expand the power bar again to use the free space!
So I expanded it again, now it's 52px, still slighly smaller than before (60px), but barely noticeable while keeping the longer tip names.
