It's hard to mess up mounting chainrings if you just stop to think. Look at the mounting holes, and both 110bcd rings will have counterbores for the heads of the chainring bolts. So both rings are mounted with the plain side to the crank spider, and the counterbores opposite each other.

Now, there's the small possibility that your middle ring was made to be the inside of a double, vs the middle of a triple. The difference is whether it has shift ramps and gates (cut down teeth) to help the chain climb up from the smaller neighbor. The inner of a double lacks those because it doesn't have a smaller neighbor.

You can also improve shifting by "timing" your rings. Many will have a mark, which can be a stamped in diamond or triangle, or a bit of a tit on the inside. This mark is aligned either with a corresponding ark on the outer or the crank arm. Timing the rings ensures that the chain shifts from the smaller timed so the teeth can slide straight in rather than bumping against the rollers.

Take your rings off, check for timing marks, flip so the C-bores are where they belong and remount, and that should go a long way to solving the problems.
