Labels are not displayed

I am using the modelling tool on Cawemo and all of a sudden labels are not displaying in tasks or on events etc. Using latest Chrome on Windows 10:-1:

Chrome Version 78.0.3904.70 (Official Build) (64-bit)

This is the same as a closed bug on github:-

Is there a workaround? How do I fix this? I have done a tone of work and now Iā€™m completely blocked out

I am not sure what it was that triggered it. I was using cawemo for about an hour and then it just stopped displaying labels I was creating on tasks, events etc. exactly as in the OP. However, when I uploaded the bpmn file to it worked fine. I did some work and then exported from and imported into cawemo overwriting the diagram that had the problem above and the same diagram no longer had the issue!
