It's probably because you haven't set the name of your workspaces correctly.
In xfce, open up Setting Manager then head to Workspaces, in the General tab you should see the list of your workspaces. Here you can change the name of your workspaces. they should match the name of workspaces in your workspace module in the polybar config file.
for example I the name of my workspaces were w1, w2, w3, w4, ...
in the workspace module I would type:

icon-0 = w1;1
icon-1 = w2;2
icon-2 = w3;3
icon-3 = w4;4
icon-4 = w5;5
icon-5 = w6;6
icon-6 = w7;7
icon-7 = w8;8

the word before ';' is the name of your workspace and the word after it is the icon of the workspace
you could also simply name your workspaces 1, 2, 3, 4, ...
and go like:

icon-0 = 1;1
icon-1 = 2;2
icon-2 = 3;3
icon-3 = 4;4
icon-4 = 5;5
icon-5 = 6;6
icon-6 = 7;7
icon-7 = 8;8
