Ballooning and Item number inside Balloon

I inserted bill of Material and did auto Balloon for my assembly drawing sheet.

In the beginning balloon was giving Item no: details, later I saw balloon is having the file name.

How can I correct this to Item no:

Below is the image of how Balloon is looking now.

Initially this was Item no: like 1/2/3/4..... inside

Now what we are seeing is my file name of each individual part.
