Pretty much any investment account in Quicken I observe this behavior.
(FYI: Quick Classic Deluxe, R65.17, Build 27.1.65.17)
Go into the register for the investment account (in my case it's a Roth, and a Rollover/IRA).
On the Action Column, click the little arrow/pulldown. Observe the list that's presented. It's about 23 items long. Note that things like: MiscExp, Shares Transferred between Accounts, etc. are not available. Now click the Edit (right-hand portion of register) and you'll see a full list. Even better, if you enter say, a:
Shares Transferred between Accounts, it gets recorded in the Register as Action: Removed
But if you try to use Action: Removed, you get a completely different option/set of fields.
You can't even type:
Shares Transferred to choose the option, you must always click the Edit, wait several seconds for Quicken (because it's so slow) and then choose the option from the "full" list.
