I am trying to calibrate my first CFL spectrum taken with the public labs smartphone spectrometer. The save fails with a permanent spinning wheel on the save button and a "Tag you've applied couldn't be saved" warning. See the attached screenshot and link to the spectra.
I am using a MacOS Sierra v10.12 and Google Chrome Version 54.0.2840.98 (64-bit).
The same issue occurs if I use Safari.
I would be really grateful for some help on what I am doing wrong.
