Steps to reproduce:

1. open hosted app (stack trace is from 18a6b21a2a8c2cf469df22fdda43648fed60e1ed)
2. Select Use Sample of Buffalo Data
3. Select Cilla
4. Fit Model
5. Select both OU anisotropic and OUF anisotropic models
6. Preview 2 home range plots
7. Click Export Shapefiles

Shapefile export works fine with multiple animals, just not multiple models per animal.

Thanks for the report! The code used individual name as shapefile name. I have updated it to include the model name and tested it works.
