 No surprise there:

No surprise there - this version is at least 2 years old, and missing a
whole lot of updates in libdivecomputer.

Try updating to the latest version of the android application from
https://subsurface-divelog.org/current-release/

The Google Play Store version is very out of date, and can not be
updated by us for the time being.
