Auto leading massively increased in Photoshop CC2019
I've just opened Photoshop 2019 after being away from work for a few days and my entire Tools and Windows appear to have re-set, causing all kinds of inconveniences, but the main problem I have is that, when I select 'Auto leading' in my Character panel, it is now setting the leading at almost 90% of the font size - for example, my Auto is currently the equivalent of 9/16pt. I've checked Paragraph and all Space Before and Space After is all set at 0pt. It was never this much before. Can anybody give me any pointers as to what is happening and how I can re-set to a more reasonable spacing, as it was in CC2018?
