Tab order brokes after doing artefacts

Hello

I am making accessible forms with InDesign. We do articles and tab orders and then we export the file to Adobe Acrobat DC and finish the accessibility.  Everything is just fine after making one text field to an artefact. After that the reading order brokes and NVDA reads the hyperlinks (inside the texts) last. Before making artefacs via Tag - reading order, everything works perfectly.  We are using NVDA to read the forms. The text field. which shoud be an artefact, is a text field where information is copying by from the first page.

NVDA reading example: text fields, hyperlink, text fields, hyperlink, text fields, text field which shoud be artefact. 

But after doing an artefact the reading order goes:

text fields, text fields, text fields, hyperlink, hyperlink, hyperlink.

This used to work earlier but I don't understand why it doesn't work anymore. Our accessibily report is telling, that this is a problem.

Is there any solution on this problem?
