Column field is black

[Adjidja_Kanda]

I can’t see any of the column fields it’s all black. I have made a new gantt project and the columns are still black however when I right click it does tell me what columns are there. How can I fix this please?

This was answered yesterday:

Headers cannot be seen

I just downloaded Gantt Project on MacOS Catalina and I am unable to view the headings as they are shown as a black bar instead. [Screenshot 2020-10-20 at 11.16.27] [Screenshot 2020-10-20 at 11.15.55]
