Manage payment and tax profiles - Why does the Submit button always disabled?

Question

Hello

I am an individual user to sell my software on the Microsoft Store.

In the Microsoft Partner Center, I see the message: "You currently have 1 enrollment(s) that require payment and/or tax profile assignments. Select payout and tax profile assignment to complete the actions."

In the Microsoft Partner Center, under Account settings, Payout and Tax Profile Assignment, I select the only row with my profile, and click Edit to open to assign payment and tax profile.

The issue is that Submit button always disabled.

My Payout and Tax Profile Assignment are completed successfully.

I am using Microsoft Edge and I cleared my Browser History.

The Submit button always have disabled Mode. Why?

Could you please explain.

Thank You
