sitedesc variable in home page title

hi there, have been using WPSSO for years in conjunction with AIOSEO but in lastest update, the home page title tag has been messed up and showing %%sitedesc%% in the title tag and can’t get rid of that variable tag.

AIOSEO seems to be handling all the title tags for all the other pages except the home page title tag. I change it on the page itself in the WPSSO seach engine title field, but the vcariable tag always shows up at the end.

I don’t see a place in the settings to turn off WPSSO for SEO title tags so not sure how to resolve this.

This just started with the most recent plugin update. Can anyone offer any advice on this please? Thanks!
