I cannot reproduce this. See below log:

I built U-Boot from the latest u-boot/master:

commit a2d051e7b6a8f87add1067d936bb0c805a47b0df
Merge: 719f421 db82015
Author: Tom Rini <trini at konsulko.com>
Date:   Fri Jul 31 10:13:07 2020 -0400

    Merge branch '2020-07-31-more-env-updates'

    - Fix EFI selftest to not force setting serial# environment (and also
      get the U-Boot prompt dynamically).
    - Support for append only environment and other related features.
    - Improved ext4 environment support
    - Fix the case of fw_setenv being used on flash devices that were not
      already locked.

Regards,
Bin
