Transfer from Checking Account Type to Credit Account Type Not "Sticking"

I am having strange problem with transfers between business accounts.

i) I have an ABC business checking account.

ii) I have an ABC business credit account.

iii) When I transfer funds from the ABC checking account to the ABC credit account the transfer initially appears in the ABC credit account.

iv) When I went to reconcile the account I noticed that:

a. The transfer no longer appears in the ABC credit account; and

b. The ABC checking account register entry has [Unspecified Account] rather than [ABC credit account] as the category.

To make matters worse, I had this problem with both companies that I track through QWin Business.

Would be great were someone able to shed some light on this for me.

Thank you.
