Farragut uses too much repair capacity?

[BPRE]

Looks like something is "funny" with the tonnage of DD Farragut when repairs are calculated. It's sitting in PH with a ton of other ships being repaired.
With the setting Normal it looks like this with 79030 tons capacity used:

If I change Priority to High I would expect another 1365 tons added to the Repair yard capacity used but it's adding 8675 tons!!![X(] so the total becomes 87705 tons.
The same increase occurs if I change to Critical. I tried the other smaller ships and they seem to act normally (2x at High and 3x at Critical (although the manual says 4x)).
