Mail marked as 'Junk' still in the 'In box'

[FredCB]

Hi, I wonder why mail that is 'Junk', and has been marked as such, still appears in the 'In Box' rather than be transferred to the 'Junk' folder as soon as it is identified as 'Junk'. This is the way it used to work, or is there now some thing that I need to address, to get this to now happen again?

Oops sorry. Totally ignorant as to how things work here, and it doesn't help being 83 years of age and not very tech savy😩
