I am making a game right now in roblox, and need to make gamepass store, however when my loop goes through it (its a table in table), it goes out of order
Example code with the tables in table

a = {
    ["5robux"] = {
        value = 10,
        name = "21"
    },
    ["10robux"] = {
        value = 13,
        name = "31"
    },
    ["15robux"] = {
        value = 20,
        name = "41"
    },
    ["20robux"] = {
        value = 25,
        name = "64"
    },
    ["61robux"] = {
        value = 25,
        name = "64"
    },
    ["50robux"] = {
        value = 3,
        name = "64"
    }


}
for i, v in pairs(a) do
    print(i, v)
end

Output:

5robux  ▶ {...}  -  Server - Script:30
50robux  ▶ {...}  -  Server - Script:30
61robux  ▶ {...}  -  Server - Script:30
20robux  ▶ {...}  -  Server - Script:30
15robux  ▶ {...}  -  Server - Script:30
10robux  ▶ {...}  -  Server - Script:30

As you see, it firstly goes to the first element, then to the last and so on
How can i fix it, and whats wrong?

Tried changing the loop, but still wrong output
