I have this issue also.  When tabbing through any transaction when getting to Categroy field it is all messed up with unrelated items plus one cannot tab out of it.  I have to click on something else and then go back to Category.  I understand that this has happened in Chrome, Edge and several others so is not a browser issue.  It is a Quickbooks issue.  It is frustrating and the work takes longer.  I hope they fix it soom.
