Unable to edit contacts

I am running two basically identical Nextcloud instances. They were both installed with Yunohost. They both are on NC version 29.0.7 (latest available for Yunohost). One is on a computer at my house for personal use, one is on a VPS for my job. Just today I noticed that I can no longer edit any contacts at all on the one for work. My personal instance I can still edit contacts. Can anyone help me figure this out?
