In the bottom of Search for Instrument - you can select if you want to preview the instruments in Search for Instrument through new mixer channels for the close mics. One scenario could be that you have low volume on the current snare's close mic mixer faders, and when you preview a stack it will (by default) create new mixer channels. If you change the "Route Close Mics to Mixer Channels" to "Existing", the stacked snare will play through the current snare channels.
When you load the stack it will also use this setting...
Maybe much information 🙂 But try it and see what difference it makes.
