All data of recorded track lost after editing description

Hi there,

I ran into a reproducible, serious problem: after editing the description of my recorded track, all data except the description of the track is lost. There is no data left except the description.
Fortunately, I was able to recover the data using Locus Map Web.

I'm using Locus Map 4.23.1 on Google Pixel 6a, Android 14, Build AP1A.240505.004.

Could you please analyse and fix the problem?

Thank you very much. I love Locus Map.
Kind regards
