PacePro giving a large number of seconds (like 32500) ahead or behind

I have used PacePro plans with navigation for a while whilst running here in Norway, on the first few meters it will say that I am 32767 (ish) or 0 ahead for the first call, but I just ignore this as it corrects by the next split. I split on elevation change.

I went to Ireland and the UK recently and the estimates were completely wrong, every split said 32500 ish ahead of behind. I thought, maybe, that I have entered goal time by mistake, but no.

Oddly it was given the average pace and next split pace correctly. It was just the ahead of behind voice prompt that was completely wrong.

Back in Norway, it is correct again.

Very confused by it should go wrong in a different country.

Everything else was fine, just the ahead or behind figures when read out.

There were two updates applied whilst I was away. But I had the issue still after the last update, and was fine back in Norway with the same version - which is 19.34
