Tables Column link to Contacts Returns No Contacts

Nextcloud Hub 8 v 29.0.4; Tables App v 0.7.5

In the tables app, I have a table with a column that links to Contacts. When I create a row as an administrator, everything works fine. I am able to type in a few letters and a list of Contacts appear. However, when I log in as a standard (non-admin) user, it does not return any Contacts when I type the same letters.

Is this a permissions issue? If so, where would I look to correct it?

Thanks for your help!

I have a very similar problem. I have submitted it as a bug report. Maybe you can take a look at it and respond there if necessary
