Distance travelled by boat does not work

[iJuju68]

Description of Bug

As soon as I add a displacement mode, the counter no longer increases; here's my configuration, I tried 2 methods with and without “ ”.
Similar problem with walking and running mode.

I'd also like to know if it's possible to combine several modes?

Thanks in advance for your feedback.
