You're probably getting a combination of direct monitoring through the interface and software monitoring. If you're inserting a reverb directly on the track, try adjusting its settings so it's 100% effect and 0% of the dry track. If you're using an effects loop, set the send on the track to pre-fader and turn the fader down. If the reverb has a predelay function, turn that down to a minimum.
The other method would be to turn off direct monitoring and decrease your buffer to reduce latency when software monitoring.
