Excel 365 simple formula between multiple excel sheets

I don't know why when I use a formula between two sheets, I can't see the cursor position in the different cells of the second sheet.

In the image the formula is in the sheet2, and I'm using the value of the cell A1 of the sheet1, but if I change to the cell A5 or other, I can't see the cursor  position:

The problem is when I use funtions or complex formulas in different sheets, I lost the cursor position.

Someting like the next image, when the cursor shows that I'm in the cell A1, and Excel uses a black marge, but using different formulas or function, today in my Excel it dosen't work:

What can I do to solve this issue?

Thanks a lot!
