I have no idea what the exact cause of the problem might be.
Upload a single page document with a table where you see this to a download service like Dropbox.
Post the link to the document so that someone can see into this.
To further clarify, my coworker and I just downloaded the MENA version of InDesign and she is having the same issue. Could it be a problem with this version?
I cannot see this behavior with my German InDesign CC 2017.1.
Did that happen suddenly out of the blue?
Or after updating InDesign? Updating the operating system?
After installing a 3rd-party plugin not from Adobe?
What is your exact version of InDesign on what OS ?
No, we noticed we cannot since recently downloading the MENA version, which we needed so we can format arabic text.
Indesign version 126.96.36.199
OS Sierra 10.12.2
It does! Weird that they just dont work in the tool bar
