@HalcyonJAC Could you create a preview URL on Admin Production pls? We don't have all the user groups set up on Develop, hence it's not possible to fully test this ticket.

@HalcyonJAC The Senior dropdown is not working for me - this should be filtered by Ops Senior Manager role. Could you fix pls?

[HalcyonJAC]

@nickaddy It has been sorted. Could you test it again, please?
