Welcome on the forum @Henk_Levels,
They should still be in the dashboard / settings of the Better Logic app. If they are missing check that you updated to the latest app update.
Then search at the forum for the script to regenerate the backup of BL variables that you should have made and restore the variables.
Or you could change to the build in logic of Homey v2 if you don’t use the really advanced BL functions and have to change/fix all flows.
