Update shows different versions

I bit the bullet and did the Sonos update after probably two years. System seems fine . I did notice that one of my subs shows version 17.2.6 and all my other 13 speakers show version 18.6. Normal or does it need to be matched up and if so, how? Thanks

It’s certainly not uncommon for older devices to be on different firmware releases. 
 

I am currently on a variety from 18.6 to 17.2.6, depending on what version is required for older devices.

A quick look at the profile in these cases helps.
