custom field list order and filter

[Dask]

Hello together,

I created a custom field with type "string" so that I can have a list for the attr "size" like "50; 56; 62; 68; 74; 80; 86; ... 140+; >140".
Issue:
In the frontend the order /sorting of the drop down list is total mixed up in the search dropdown list (searchable = 1) like
86
80
74
92
98
116
>140
128
134
122
+140
62
68
104
110
140


In the backend, when I am creating a new product and choose the size for the product from the dropdown list by the custom fields, everything is fine. there is the right sorting list.
So, how can I fix this issue?

Thanks for helping me.
Marcus

so, no answer yet
But I also have another strange thing. The values of the list are not they should be.
See the screenshot I made.
Is this a bug or a feature?

I think you should use the 'Multi Variant' custom field type for your purpose. Example screenshot below.
