It would normally be best to move the drumline soundfont *below* the default so it doesn't take over the default sounds, then use the Mixer to select the appropriate sounds for the specific instruments you need them for. The drumline soundfonts will be listed at the end, after the sounds from the default soundfont.
If you need further assistance, please use the Support forum to ask for help, not the issue tracker. Or, from with MuseScore, Help / Ask for Help, not Report a Bug.
