Extract and save references from HTML / metada cant be change when ORCID number is confirmed by author

Formatting (italic, bold) of references is lost during the extraction of references copied from docx file to the reference metadata field (OJS 3.1.2). To retain this formatting usually we are using free HTML editor https://html5-editor.net/ and references are copied and pasted as HTML code. This process works well, and formatting is retained.

I found that references can not be extracted from HTML. After clicking the Extract and Save refernence button nothing happen, the window stay open.

Extraction from docx or txt is working.

Another issue is related to metadata

It is not possible to edit metadata when ORCID number was confirmed by author.

Devloper tools:
