Root note and tune wrong when importing sample from Wavelab?

I seem to have a strange problem, not sure if this is a bug or what.

I have a bunch of samples that were created in wavelab Elements 8. The samples have a key set and a detune. For example C1, -2. When I import the sample into Halion 5 the root key gets set to B0 with a tune of 98 instead of a root key of C1 with a tune of -2. If I manually correct them they sound right, if not they are off.

My samples in wavelab elements 8 that have a key set and a positive detune work correctly. For example a key set to D0 and a detune of +5 show up correctly in Halion 5 when imported.

Not sure if this is a wavelab issue or a Halion issue.
