I just bought Mac 2020 version today 3/3/21 to run on my MacBook Pro 2020 which came with Big Sur. I do have the color problem, and blank notation page and blank lead sheet. Can't close lead sheet

Here's my Mac spec:

MacOS Big Sur 11.2.2
MacBook Pro (13-inch, 2020, Two Thunderbolt 3 ports)
1.4 GHz Quad-Core Intel Core i5
8 GB 2133 MHz LPDDR3
Intel Iris Plus Graphics 645 1536 MB

Thanks for looking into it.
