Ive noticed while playing around with my database that after 130k hands of 200$ NL 6max I'm deep in red for river calldowns. What I mean, is that I've lost about 6160$ in 870 hands where I ended up calling the river bet, which is at -177 PTBB per 100 hands. So is this number standard or am i calling river too often with weak holding? Similar problem appears to be with my river bets, where when I bet, check raise, raise or push, I win the showdown 80% of time. So here it seems that I'm not value betting river enough?

Does this -177PTBB per 100 hands apply to EVERY hand where you called on the river? If so, then I don't know how this can be anything other than a leak. Every play you make needs to be 0 EV or better.
