Dynamic spelling underline is asking me to change all first letters to uppercase
I turned on dynamic spelling to see potential mistakes in the text, but it is asking me to change all first letters of words to uppercase, even when they are not at the beginning of a sentence. This has been really annoying because there is so much underlined text that I can't really pay attention to the red ones, which are actually potential grammar mistakes. Has anyone else experienced this problem and knows how to fix it?
The graph style is set to my language. Only that came to my mind is that InDesign thinks it's all names because it has bad vocabulary in my language, so it asks me to change the first letter to uppercase so the word makes sense to the system. But that would be so stupid, why wouldn’t it underline those words in red instead?
