Capacity usage in SNP PPM's

When I am trying to look at capacity data in Planning Book - Capacity view.

the ppds orders do show the correct values (in hours). however, the snp orders shows the value in days.

it is not useful. because if there are buckets in which both the order types are present (SNP and PPDS), the capacity usage in the planning book in hours would be inaccurate. Is there a setting so that the capacity for snp orders can be shown what it actually is (96 hours instead of 4). what it means by 4 could be 4 days. but then how can one say. teh capacity view does not specify. so the percent utlization becomes garbled. Am i missing something?
