Bug? with irrigation total when pausing the run?

Started irrigation for 2 zones, both zones were about 70% full.
Both ran for 10 minutes. Zones are the same size.

However, during the first zone, I paused it when it was running for 7 minutes. I paused it for 30 minutes, after which it continued to run for 3 minutes, and the other zone for 10 minutes.

After checking the zone totals, the first zone is still at 70% while the second zone is at 110% .

Any suggestions/clues? Will try the same again in a few days if the same thing will happen…
