Dotted Minim instead of tied notes?

Hello,

Can any one tell me how I can convert this tied note (the red voice) so that it reads as a dotted minim?


And here also?

I would prefer that this note to read as a minim rather then two crotchets tied?

As you can see by my preferences with the first screen shot, it appears as though I have selected the correct notation option, but it doesn’t appear to make a difference.

Any suggestions out there?

Thank you! Thank you!
