Power Query not loading functions

Hi,

I'm using MS Office Home & student 2019. I want to transform the data from my current workbook. I open the Power Query editor as a Blank query and while typing the function "Excel.CurrentWorkbook" in the formula bar, the functions don't show up as I type. Instead, I have to type it manually keeping in mind it's case sensitive. Once I type the function, it will ask to Invoke parameters and then it gets the data from the current workbook. 

Can anybody please help me with resolving this issue?
