Whenever I start kdenlive version 20.04.3 with an existing project file, once
the file is loaded an asterisk appears next to the filename in the window
border, indicating that it has been changed. An examination of the project as
displayed shows no obvious changes. I don't understand why changes are
indicated since the file is freshly opened. Can someone please explain what
is going on here?

I am running Fedora 31 with kernel 5.8.6-101.fc31.x86_64l on an HP Pavilion
a6209n with an AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ CPU. Software is
current, I just updated everything this morning.
