Forms :: How To Refresh / Requery MSysObjects In Combobox

I set up several combo boxes to display Tables from msysobjects. The record source is using a WHERE clause to display certain tables both Linked and Local. Occasionally, when clicking the dropdown arrow, the box only displays local tables. This situation seems not to matter whether tables have been newly linked or unlinked. despite having both a me.requery and a me.refresh in the code and/or even clicking the Refresh All button on the ribbon menu, the form does not seem to update the combo box to display both linked and local tables.

In further testing, it seems that it is not a form issue because I took the SQL statement I used as the record source and created a new query with the sql string. The query behaved the same as the combo box, only listing out local tables.

My current work around is to close the database and reopen, then all is well. Hopefully there is another way to get the linked tables listed without this drastic step.

Don't think it's necessary, but here is the sql statement. Type 6 is linked.

Code:
SELECT msysobjects.name
FROM msysobjects
WHERE msysobjects.[flags] = 0
AND msysobjects.[type] in (1, 6)
AND Right([name],7)<>'_SOURCE'
AND Right([name],4)<>'_OUT'
AND msysobjects.name not in ('tblImport','tblImportFormats','tblUniversal') OR msysobjects.database=gblprojectname()
ORDER BY msysobjects.name, Right([name],7);
