.browserslistrc Not Acknowledged by doiuse.

I have a .browserslistrc file with targeted browsers based on legacy and modern browsers. The entire file isn't being found by the npm module. Anyone have an idea as to what the issue is?

.browserlistrc file content:

```
[legacy]
last 2 versions
firefox esr
not dead
> 1%

[modern]
last 1 chrome version
not chrome < 60
last 1 firefox version
not firefox < 54
last 1 safari version
not safari < 10.1
> 0.2%
```
