Wrong distance from ZWIFT

Hi all! I don‘t know if it is actually a problem of ZWIFT, but it occured since the last ZWIFT-update. The distance of the workout is wrongly transfered to GARMIN Connect. Like I made 103,53 km in ZWIFT and in GARMIN Connect it is displayed as 103.530,00 km!!
What is most anoying is, that GARMIN Connect does not change the wrong numbers, when you edit them! So maybe it is a problem with GARMIN Connect, but there was no softwareupdate and it worked in the past…
Help is highly appreciated!
