My two cents: I am a pension actuary and see the performance of funds on a daily basis. Is it normal to see down years? Yes, absolutely. It's a function of the directional bias of how the portfolio is invested. In the case of a 401(k) that almost always mean a positive directional bias (being long). Now, in your case I see two issues:
The amount of drawdown over one year. It is atypical to have a 14% loss in a little over a year. Given the market conditions, this means that you nearly experienced the entire drawdown of the SP500 (which your portfolio is highly correlated to) and you have no protection from the downside.
The use of so-called "target-date funds". Their very implication makes no sense. Essentially, they try to generate a particular return over the elapsed time until retirement. The issue is that the market is by all statistical accounts random with positive drift (it can be expected to move up in the long term). This positive drift is due to the fact that people should be paid to take on risk. So if you need the money 20 years from now, what's the big deal? Well, the issue is that no one, and I repeat, no one, knows when the market will experience long down moves. So you happily experience positive drift for 20 years and your money grows to a decent size. Then, right before you retire, the market shaves 20%+ of your investments. Will you recoup these damages? Most likely yes. But will that be in the timeframe you need? The market doesn't care if you need money or not.
So, here is my advice if you are comfortable taking control of your money. See if you can roll your money into an IRA (some 401(k) plans will permit this) or, if you contribute less that the 401(k) contribution limit you make want to just contribute to an IRA (be mindful of the annual limits). In this case, you can set up a self-directed account. Here you will have the flexibility to diversify and take action as necessary. And by diversify, I don't mean that "buy lots of different stuff" garbage, I mean focus on uncorrelated assets. You can get by on a handful of ETFs (SPY, TLT, QQQ, ect.). These all have liquid options available. Once you build a base, you can lower basis by writing covered calls against these positions. This is allowed in almost all IRA accounts.
In my opinion, and I see this far too often, your potential and drive to take control of your assets is far superior than the so called "professionals or advisors". They will 99% of the time stick you in a target date fund and hope that they make their basis points on your money and retire before you do. Not saying everyone is unethical, but its hard to care about your money more than you will.
