1. Check and remember actual **COB** and **IOB** on the **AAPS'** homescreen.

2. Depending on the pump, the carbs in the Treatments tab might show together with insulin in one line or as a separate entry (i.e. with Dana RS).

3. Remove the entry by firstly 'ticking' the waste bin on the top right corner (see above photo, step 1). Then 'tick' the faulty carb amount (see above photo, step 2). Then 'tick' the ‘waste bin’ on the top right corner (step 1 again).

4. Make sure carbs are removed successfully by checking **COB** on **AAPS’** homescreen again.

5. Do the same for **IOB** if there is just one line in the Treatment tab including carbs and insulin.

6. If carbs are not removed as intended and additional carbs are added as explained in this section, the **COB** entry will be too high and this could lead to **AAPS** delivering too much insulin.

7. Enter correct carbs amount through carbs button on **AAPS’** homescreen and set the correct event time.

8. If there is just one line in Treatment tab including carbs and insulin the user should add also the amount of insulin. Make sure to set the correct event time and check **IOB** on homescreen after confirming the new entry.

2. Open **Treatments history** (drawer menu → *Treatments history*), tab **Carbs and bolus**. Depending on the pump, the carbs might show together with insulin in one line or as a separate entry (i.e. with Dana RS).
