[Bug]: Map array fields in PDFs

[BroderPeters]

Expected Behavior

In a PDF file like this, form fields are provided as array (e.g. in scribus a field is named acrobatics[1]).
New Character.pdf

Mapping values from foundry to acrobatics[1] maps and exports the value correctly.

Current Behavior

Trying to map it currently doesn't put out a value. Neither in the module form nor in the PDF.
Am I missing documentation or a specific feature for this?

View in "Export to PDF" screen in FoundryVTT:

Values in Developer Console of PDF Sheet:

Steps to Reproduce

For this specific one, I started to re-map the existing mapping for Starfinder from this repository, as the linked PDF from the README is not available anymore.
Picking the PDF template from https://hephaistos.azurewebsites.net/ I started mapping the values accordingly and stumbled upon the mentioned array in the PDF form.

I've used this mapping (saved as json because GitHub only allows certain file uploads here) and the before mentioned PDF.
