Numbers showing as symbols when using Edit and adding Text

I have a PDF document. I want to add a text box and I used 'Edit' then 'Text' under ADD CONTENT. The letters come out OK but numbers are showing as symbols. I searched for the issue and found something to do with changing the language from English with Arabic Support, but that hasn't worked. Also if I type hyphen in the text box, it starts typing the letters from right to left. Such a simple task is so painful and I end up having to use InDesign. The image attached I tried to type 'abc-12345' and you can see the result.

I am so frustrated by Adobe Acrobat. It is so buggy in the last year or so and trying to contact Adobe is impossible. This is a paid subscription and the programme rarely works how it used to. It wastes so much time in my work trying to resolve the issue.
