DataGrid Column Template crashes when loading data

Using the most recent version (18.1.44) of the DataGrid, I am unable to render custom column templates. It throws this console error:


template.js:71 Uncaught TypeError: str.match is not a function
    at evalExp (template.js:71)

Downgrading to version 17.4.55 fixes this issue to me. It's a little strange since all the demos running 18.1.44 seem to work, so it might have something to do with my configuration. Attached is a screenshot of my render function.
Note: I've tried a clean install of all the Syncfusion packages, and it was still throwing this error. React version: 16.13.1
Built using Webpack 4.42.0
Version 17.4.55 works for our needs right now, just figured I'd report the issue. If you need any more details, let me know!
