Good day, adl,

Thanks for getting in touch with us today and allowing us to give you a hand.

First, let's make sure your QuickBooks version is updated the its latest release. This way you're able to download the latest updates and bug fixes available for the program to function as design. Also, please be reminded to create a back up copy of your company file before doing any troubleshooting steps to avoid any accidental data loss.

Secondly, missing entries or list elements are sometimes caused by damaged lists. The damage, however, can often be repaired by re-sorting which puts a list back to its default order. Let me walk you through the process:

1. Go to the Lists tab.
2. Select Item List.
3. Choose the Item button below.
4. Click on Re-sort List.

After re-sorting the list, try checking if it is now saving the notes normally. If not, we can try merging the affected items. Here's how:

1. Go to the Lists tab and choose Items.
2. When merging the items, make sure they are of the same type.
3. Hold the Control (CTRL) key and select the damaged item.
4. Select Edit Item.
5. Add an asterisk (*) to the name of the item, then select Cancel.
6. Hold the Control key, then select any item.
7. Select New Item.
8. Choose the appropriate type, then enter the original name of the problem item.

9. Select Ok.

10. Hold the Control key again, then select the original item.
11. Choose Edit Item.
12. Remove the asterisk (*) from the item name and select OK.
13. Select Yes to merge the two items.

That should help you circumvent the hurdle your getting with saving your item notes. If you have any questions about the process, please feel free to let me know by mentioning me anytime. Have a good one!
