Is it an additional transient or the only one (per kick hit)?
If it's the only one and they are all off by exactly the same amount use the right click menu to select all and move them all en masse. If it's an additional marker try using the filter section to filter them out. I would think that the resolution filter would work well in that situation, quarters for example but of course it will depend on the kick drum pattern.
You may be able to use that to reduce the work load a little if not fix it completely.
It might also be worth bouncing the kick drum down to a clip. In my experience with audio snap a little bit of clip housekeeping such as trimming and bouncing to clip makes a huge difference to how successful audio snap is especially on live material.
