2. WAs not able to understand the query here . Is it the issue with the space between group image and header?
Can you please elaborate more on this ?

to quick fix this add this css in your wp-admin -> appearance -> customize -> custom css :
#buddypress div#item-header div#item-header-content h3 {
display: block;
}
4. Unable to replicate the issue :
