Keyword "where" doesn't work for command "print"

In “/ip firewall filter” I tried to print rules list filtered by “action”. Nothing displayed for definitely existing actions. WinBox shows these rules, but terminal doesn’t.
Printscreen is attached (Winbox and teminal output with filtering by action=accept).
What is wrong?

Try quoting it, see if that works:

print where action="accept"

Yes, it works with quotes

Thank you
