Logging error

[waszil]

I'm using python 3.7.7, sphinx 3.0.3 and the latest automodapi.

The following problem occurs:
I get these kind of warnings:
"WARNING: Found additional options members in automodapi"
however it causes a logging error:
TypeError: not all arguments converted during string formatting

I played around with it and I could fix it by this, as it seems that arguments are passed to the string that have no % formatter placeholders:
