How to retire fixed assets (sale) when the quantity is zero

Hi all,

we have some fixed assets that we need to retire. however it does not show up in the list of items in the retirement window. I have noticed that these items do not have quantities.. they were capitalized with an amount and zero quantity.
Does anyone know of a work around this?

Thank you
