WSPR requires lower sound card gain?

I use a SignaLink USB sound card, and it works fine with WSPR 2.0, HRD, some of the MM programs, etc. There is one odd difference between WSPR and the others. All the others use approximately the same gain for both RX and TX. WSPR requires much lower settings, very roughly 10db, for both to prevent overloading for RX, and to obtain the same power for TX. It is a minor issue, especially since I have some software to reset the mixer gains automatically, but I was wondering if this is the normal experience?
