Disable onpage analysis causes js error

Hi, i am unable to use the title and meta description editor when on-page analysis is disabled.
The following js error is thrown:

Uncaught TypeError: Cannot convert undefined or null to object

The error is thrown in assessor.js line 3302 (when using chromes pretty print to reverse minification). the following line is highlighted as causing the error:
C.default)(this.researches, Object.keys(rankMath.assessor.researchesTests))

I need to disable on-page analysis because it is showing big red warnings that wont go down well with my client!
They are irrelevent because they appear on every page, including ppc landing pages and other non seo focused pages.
Even on SEO focused pages, i would not want them visible as they are guaranteed to tempt the client to mess up sales copy etc.

Apart from this rather critical (for me) issue, great job, plugion looks awesome.
