Can't find out multiselect field values in proper order after saving the record

Hello,

As per requirement, in Item record, I added a multi-select field and a custom list is selected as source of the multi-select field values.

When, I am going to create a new Item record, the multiselect field values are showing in proper order as defined in source list. Suppose, I selected any 3 Items on that multiselect field.

Now, the problem is, after saving the Item record, those selected 3 items (in the multiselect field) are not showing in the proper order.
But, I have to show this in proper order.

[ex: Say, MultiSelect field values : A
                                               B
                                               M
                                               S
                                               P
