Model Factsheet - General: More than 9 authors are dropped

[dlr-cjs]

Description of the issue

When you add more than 9 Authors to a Model Factsheet, all authors exceeding 9 are dropped on submit.
They do not appear in the updated factsheet, and when re-editing the factsheet the previously entered fields (after the ninth one) are missing.

We have about 15 authors at the moment four our model and would like to name them all - if possible.

Steps to Reproduce

1. Enter more than 9 authors in a model factsheet
2. submit
3. the 10th and forthfollowing authors are removed

Ideas of solution

Check hard coded author limits or check for single-digit author identifiers.

If an author limit is intended (but why should it?): State that limit in the help text, do not allow to add further fields that are dropped.

Thanks for pointing that out! The factsheets really need reworking :). Unfortunately, we don’t have a project in place to do that.

I’ll try to fix the error anyway.
