Drop down expects unique values as choiceValues. In your case 78 is repeated twice. 
 Please check if by any chance count(local!getRegion) = 77. If it is so, the choice value array will have 78 inserted which is already present as part of choice value. 
 Also, I suggest to use 0 or any other uncommon number to be inserted for "Select All" logic. Because, some times the result of count(local!getRegion) can be same as the id value in choice values.

you have duplicate choice values , one of them is 78. Try to run the rule independetly which is fetching the values for drop down and check what could be reason for getting duplicate values. 
 
 Or share the code for local values which you have created for us to help you further

Is your first component multiselect ? Are there two values in first component which could bring the same value for 2nd component. 
 try running your rule with that values as parameters for 2nd component values. If that is what happening, you would need to pass unique parameters as input for rule. Use union function to remove duplicate values

There is a duplicate value in your list of choice values, and you have to get rid of it. union() seems to be a good approach, but it really depends on where you use it. 
 There is not much we can do here. We have no idea what you are doing and where your data is coming from.
