Tabular inline form bug

[hkokur]

Hello,

we switch the grapple to jazzmin for admin panel and we use many tabularinline class in the admin.py.
I figure out the formsets number is the less(-1) than the form number that shows in the ui.

it is a tabularinline form and extra field is 1. When i save the form, only upper one(value 1) saved to db.
When extra_fields=0, db saving didn't occur. Also in the admin model, i print the formsets and formsets include only one form but it should include both forms.

I continue to the trace source code. If i figure out the source of the error, i will try to fix this.
