Disabling layers in the Data to Export tab in the Export to STEP Options dialog was being used in an attempt to prevent some components from being included in the STEP translation process, but these components were showing up when opening the STEP file.
Solution
This is working as designed. Layer filtering is not supported at the component level. This is only supported at the part level or top assembly level. A workaround for this case is to use suppression by arrangements in order to have control over which components are exported in the STEP translation.
