2013 Txc 250r Oil Leak

I picked up my first bike used with only 14 hours on it. The previous owner wrecked once and put it up. The bike virtually looked new except the few scuff marks from laying it down. First thing I did was change all the fluids on it. I took it in to my local husky dealer to just have the bike looked over to see if there was anything noticeable that needed to be addressed. The day before I took it I had a quick 15 minute ride to cycle all of the new fluids. I noticed that the countershaft was leaking some oil on the sprocket and chain. The dealer replaced the countershaft seal (they didnt have the exact seal but had one that fit). I took it out for about 2 hours after I picked the bike up and there was oil around the starter wire so I assumed I had a leak with the starter cover. Turns out the countershaft seal is leaking again and I have purchased the exact seal for the bike. The Husky dealer said they couldn't see any leaking and the bike looked fine. I am having them replace the seal anyways since they were already doing chain and sprockets. Has anyone else had a issue similar to this? It isn't a ton of oil but enough to get on the chain and be slung on the swing arm and drip onto the shifter.

I've had many countershaft seals leak on many different brand bikes. A lot of dirt and stuff gets behind the sprocket and tears up the seal. But a brand new seal shouldn't leak. Maybe the dealer messed it up when installing.

I’m chalking it up to wrong seal and put in wrong. I’m hoping the new one fixes the issue. If it doesn’t any thoughts on what else could cause it?
