Problems while opening .xlsx files on Windows 10 devices

I can't open .xlsx files again on my Lumia 950 and my tablet.
First of all I had problems to download the file from Facebook messenger. With the help of my Lumia 925 and Windows 8.1 I could finally get it to OneDrive.
I was able to open the file on the 950 as well as the tablet. Today I wanted to open the file again - didn't work. I get the message that it won't open due to "older graphic files"
Any ideas?
