Yes it is an issue because the error bars on both these values is smaller than the difference between the two. So something is going on: either something a bit boring like a systematic measurement error or maybe our cosmological model needs to be refined, or something else we haven't thought of yet. This is really good news though, it means we have a clue to help us improve our understanding of the Universe. We were at a point in Physics where our best theories could predict almost all the measurement data we could throw at them. Discrepancies are the beginning of new and better theories, yay!
