ABRP routed me off and immediately back on a highway

I recently did a cross-country drive traversing the US from Massachusetts to California along highway 80. At several points during the trip, ABRP routed me off the highway and immediately back onto the highway at the same on/offramp.

I don’t know exactly when/where this happened, but the commonalities I noticed are areas where the on/offramps are relatively short, straight, and parallel to the freeway. It did not happen in populated areas or with cloverleafs etc.
