Positive Utility for Logit, Negative Utility for HB

Hello everyone,

I'm currently fielding a CBC study and recently ran a Logit and HB analysis.
The results show a positive utility based on Logit and a negative utility based on HB for one and the same attribute level.

Level 1:
HB -> Utility = -25.44 / Std.Dev. = 31.59
Logit -> Effect = 0.155 / Std. Error = 0.213 / t Ratio = 0.727

Level 2:
HB -> Utility = 14.28 / Std.Dev. = 18.80
Logit -> Effect = -0.043 / Std. Error = 0.113 / t Ratio = -0.376

Level 3:
HB -> Utility = 11.16 / Std.Dev. = 18.48
Logit -> Effect = -0.112 / Std. Error = 0.113 / t Ratio = -0.994

Can someone explain to me this result?

Thank you very much in advance!
