I think (im new in python) im using the github repo.
In all the cases i follow the installation steps on the readmes.
To give u an example, on cert-issuer:
git clone https://github.com/blockchain-certificates/cert-issuer.git && cd cert-issuer
python setup.py install
cert-issuer -c conf.ini
This was made on a new conda enviroment (for each github repo cert-tools, cert-issuer) with python 3.10.
After install i had to solve some dependencies issues.
Im kinda abusing of your help here but i had time to try the solution on changing the orders in the context to solve the display issue (i did it manually, in the template made by cert-tools).
The cert after the change

}
And when i try to issue it

Im doing something wrong? Are we using the same version of PyLD (this is a dependency that i have to downgrade) and/or python?
thanks & sorry for bothering to much,
6eer.
