Duration datatype and formatting errors

Hi, I'm building in powerbi from an excel data source. The [h:]mm:ss format is giving me issues. Powerquery interprets this as a Time datatype and makes a duration of 0:10:19 look like 12:10:19 AM. While i understand that's fundamentally the same thing, it's being weird if I force it to a decimal (representing decimal days).

[h:]mm:ss in excel:

After forcing [h:]mm:ss to decimal days, powerquery makes it just different enough I can't really use it. Any ideas? 

Thanks!
