• This is not a feature request (existing functionality does not work, not missing functionality).
  I will request features on forum or via support.
• I've searched and did not find a similar issue.

Bug in mobile app

Describe the bug
After enabling contact sync, many of my contacts suddenly had tons of empty "organization" fields in them.

To Reproduce
Steps to reproduce the behavior:

1. Enable system contact sync
2. Use phone for a while
3. open contacts, notice that some of them have tons of "organization" fields that are empty

Expected behavior
No empty fields should be saved to contacts

Smartphone (please complete the following information):

• Device: Pixel u
• OS: GrapheneOS
• Version v244.240912.0

Additional context
I had to disable contact syncing in tuta, export my contacts to a .vcf, then on my computer run sed -i '/^ORG:\s*$/d' contacts.vcf, delete all my contacts, and import the updated vcf. Even then I still see a bunch of contacts with the empty Organization fields

Hey, I'm sorry but I feel like I do not fully understand the issue. Are you seeing these empty Organization fields in the contacts on the Tuta app or on your phone's contacts app?

I think some screenshots showing the issue (with private information redacted, of course) would be really helpful.

I'm seeing it in my phone contacts app, but not tuta

We have had some other people complain about issues with our contact integration with GrapheneOS (#6568 ), so we are going to be looking into this more closely soon. Thanks again for the report.

Same goes for CalyxOS
Almost all contacts have like infinite organization fields

I could check the ones without the many fields, maybe they are different.
What I first saw is, when I gave them an organization it only doubles the field.
