High levels of LO Leakage - mini LimeSDR

Dear All,
I am using LIMESUITE and SDR-Console; high level of LO leakage is observed. What should I do to get rid of the spike? Here is the observed spectrum:


You can set sample rate twice higher and then use only left or right portion of the spectrum. It is possible to use DC cancelation math function if software have one but only for minimizing leakage efect (also usefull signal will be attenuated as wel).
