Question about version numbers

Hi,
i am building /e/ now for around a year now with docker and every build i made was outputting the correct branch name in the name, for example e-0.23-q-20220404805-UNOFFICIAL-beryllium.zip (which was my last consistent build like that).
a week later it suddenly started to output the build with the 1.0 version tag e-1.0-q-20220413819-UNOFFICIAL-beryllium.zip.

currently my env vars look like this (proprietarys are included via my local manifest):

BRANCH_NAME=v0.23-q
DEVICE_LIST=beryllium
SIGNATURE_SPOOFING=restricted
CCACHE_SIZE=100G
OTA_URL=https://OTAURL.FQDN/api
REPO=https://gitlab.e.foundation/e/os/releases.git
WITH_SU=true
INCLUDE_PROPRIETARY=false
ANDROID_JACK_VM_ARGS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx18G"
SIGN_BUILDS=true

Is this an intentional behaviour?

Thank you,
Alex
