Note, this isn't caused by a callable {{{default}}} argument, rather a string. My initial thought is that this has something to do with the conversion process of a given string value into a {{{timedelta}}}, etc., but I haven't had a chance to really dig in, yet. I just barely finished work and I have to run a bunch of errands, or I'd dive straight into the code. However, I wanted to at least get the bug report in here right away."
