Voiceover reading all punctuation, please help

Voiceover now reading ALL punctuation no matter which of the 3 settings is selected in settings>voiceover>verbosity>punctuation>active punctuation group>none. This started yesterday during use and I have spent the past 2 days trying to figure out why this is so. I think I was using the shortcuts app at the time, but nothig to do with settings. I have an iphone 8 running the latest software. Does anyone have any ideas? Many thanks
