Formatting issues in Word

Hi all,

Since the last couple of updates, I have had formatting issues that are extremely disruptive and frustrating. For the past year or so I've been working around them, hoping a solution would become apparent, but it's now at a point where I really want to try to see if there is a fix. I am on Windows 11/Office 2019 and it should be the latest update. 

One issue is whenever I try to write a heading (using Center + Bold + Italics), the new paragraph beneath the heading is automatically centered, even after I turn off centering. A possibly related issue is that if I make a block quote it also throws the formatting off, to the point that when I write a following paragraph I cannot even manually make a paragraph indent (meaning the Tab button just does nothing). To fix it, I have to copy and paste a previous paragraph into the space following the block quote, which is the only way I could find to restore the formatting. I have not, to my knowledge, adjusted any auto-correct or template options that could be causing the issue. Formatting only became a problem for me following a relatively recent update. 

Thank you in advance,

Chad
