ABRP repeatedly routes through exit and entrance lanes without leaving the motorway

On several recent trips using ABRP Premium with CarPlay, the navigation repeatedly instructed me to take a motorway exit. Instead of actually leaving the motorway, the route continued on the parallel exit lane and then immediately merged back onto the same motorway via the entrance lane.

These detours were unnecessary, as I effectively remained on the same motorway the entire time. Initially, I followed the instructions without questioning them, but after reviewing the route more closely on subsequent occasions, I noticed that this behaviour occurred multiple times and appears to be a routing bug.

My assumption is that these locations often experience heavy traffic, and some drivers may use the exit and re-entry lanes as a shortcut to bypass congestion. However, this is only speculation on my part. I wanted to mention it in case it helps identify the cause of the routing behaviour.
