dotman seems unable to execute the add_env function properly

Describe the bug running dotman the second time I end up in the initial setup again.

I found out that apparently the add_env function is not being executed as it should.
I guess the variables DOT_REPO and DOT_DEST are somehow known via some declaration within the script and therefore the check [[ "$DOT_DEST" && "$DOT_REPO" ]] && return in line 89 never fails and likewise the rest of the function (with adding those to ~/.bashrc never runs. I could not solve this though

expected behavior dotman would recognize that it ran alreay and therefore throw me into the regular interface, not the initial setup again and again

To Reproduce Steps to reproduce the behavior:

sh -c "$(curl -fsSL https://raw.githubusercontent.com/Bhupesh-v/dotman/master/tools/install.sh)"
cd ~/dotman && mkdir ~/.dotfiles && ./dotman.sh
source ~/.bashrc
./dotman.sh

Expected behavior A clear and concise description of what you expected to happen.

Desktop (please complete the following information):

manjaro,bash: 5.2.15(1)-release
ubuntu 22.04, bash: 5.1.16(1)-release

Additional context I tested this on my local manjaro. As I failed constantly with trying many things to troubleshout and also because am running oh-my-bash there i did another test inside a fresh ubuntutu 22.04 lxc container. Here is what I got there (same behavior).
