[Bug]: Loss of active material for primary and secondary material missing in solution variable

Python Version

3.11.9

Describe the bug

Hello,

I am using the composite electrode notebook. https://docs.pybamm.org/en/stable/source/examples/notebooks/models/composite_particle.html

I am trying to access the loss of active primary and secondary material from the solution instance, e.g.,

solution[0]["Loss of primary active material in negative electrode [%]"].entries

I am getting the following error

KeyError: "'Loss of primary active material in negative electrode [%]' not found. Best matches are ['Loss of active material in negative electrode [%]', 'Loss of active material in positive electrode [%]', 'Loss of lithium due to loss of primary active material in negative electrode [mol]']"

Regards, Satish

Steps to Reproduce

use this notebook

https://docs.pybamm.org/en/stable/source/examples/notebooks/models/composite_particle.html

and try to access the following variable from the solution instance e.g. solution[0]["Loss of primary active material in negative electrode [%]"].entries

Relevant log output
