'Updates' dashboard not showing available updates

STR:

1. Install PMM 2.6.0 (docker/OVF/AMI)
2. Enable laboratory repository:

     sed -i'' -e 's^/release/^/laboratory/^' /etc/yum.repos.d/pmm2-server.repo

3. Open Home dashboard

Given result: there is no "check update" button and "last check" info. The whole footer was deleted somehow. See screenshot 1

Expected result: Last check and check button is displayed See screenshot 2

Additional information: I did some research and the last build with the footer was on May 5th
