Unable to De-select "is Administrator" in DVLS for an Entra-Synced Group

We currently have 2 Entra-synced groups into DVLS, one for Administrators and one for Users. We since then found out that Administrators have access to all entries in PAM vault, so I tried moving myself from Administrators to Users, but doesn't seem to have made a difference. So my next step was to de-select "Is administrator" tickbox within the group and then specifically assign permissions to the group. However when deselcting and trying to save settings we get the following errors:

TypeError: Cannot read properties of undefined (reading 'netbiosName') at i.onSave (https://<SERVERNAME>/dvls/chunk-YGRHIQBO.js:1:91037) at https://<SERVERNAME>/dvls/chunk-YGRHIQBO.js:1:83874 at Tf (https://<SERVERNAME>/dvls/chunk-4HFZZ7HS.js:7:74231) at Object.o [as next] (https://<SERVERNAME>/dvls/chunk-4HFZZ7HS.js:7:74400) at Ui.next (https://<SERVERNAME>/dvls/chunk-4HFZZ7HS.js:3:3484) at be._next (https://<SERVERNAME>/dvls/chunk-4HFZZ7HS.js:3:3208) at be.next (https://<SERVERNAME>/dvls/chunk-4HFZZ7HS.js:3:2935) at https://<SERVERNAME>/dvls/chunk-4HFZZ7HS.js:3:5944 at zt (https://<SERVERNAME>/dvls/chunk-4HFZZ7HS.js:3:2326) at ya.next (https://<SERVERNAME>/dvls/chunk-4HFZZ7HS.js:3:5783)

I've replaced our server URL with <SERVERNAME> just to clarify that it's now actually saying that/using that variable
