Yes, so in this case investors are instead placing more of their capital in liquid assets, like public equities. With investors optimistic about the economy, keeping in mind that coupon rates rise during good economies, we would expect higher yield rates in the short term with optimistic investors having both the expectation that equities will outperform those bonds (so capital is allocated away from bonds) and secondly that interest rates will rise as the economy improves. This is exactly what we see when we look at the 1-mo to 1-yr bonds.
Coincidentally, the Fed just announced that interest rates aren't expected to rise this year, so we should see a decrease in the yields of the 1-mo to 1-yr bonds.
