FWIW, if you hover on the screenshot it is from version 2.4.
If you download the source code for calligra and go into the "flow"
directory they
talk about "Kivio" and not calligra-flow. So, is it possible that
"flow" has been
superseded by
koffice-kivio-3:1.6.3-47.fc26.x86_64 : A flowcharting application
Thanks Ed, this look like the case I will give that a try.
Thanks Again
