Seems like showCalculatedValuesButton option is not working for flat layout. I've created a fiddle for it:

If fix is going to be added, please, let me know when it's done.
Hello, Artem,
Thank you for reporting about that bug.
The fix is going to be provided with the minor update ETA Dec 30.
Our team will inform you when the version with a fix will be available.
For now, we would like to kindly can suggest a workaround through CSS; the following code hides unwonted button only for flat view:
#fm-pivot-view #fm-fields-view.fm-flat-fields .fm-popup-header #fm-btn-add-measure {
display: none;
}
Check out an example we have prepared for you.
Feel free to contact us in case of additional questions.
Kind Regards,
Illia
