When updating holdings and transactions from Fidelity, Quicken does not recognize holdings for Spaxx. It also reports holding Fbalx instead of the accurate one which is Fxaix. It wants to do place-holding entries. It also records dividends for Fxaix as being attributable to Fbalx. I have not owned Fbalx for several years however this problem began some time last summer. These are all mutual funds and set up as such on the security list. I have removed Fidelity from downloads and then re-added. The problem persists. My current version of Quicken is R53.32 I use Windows 11.
I reviewed FXaix and found the box noting that it is matched with online security is grayed out and cannot be checked. However the box for Spaxx is checked.
