As Editable templates were not supported in AEM 6.4.2 (But now supported with AEM 6.5.5). So the issue might be your component wont be the part of the Policies. So to access policies you need to access it from Editable templates but as that option is not available in AEM 6.4.2 with SPA. In this case you need to navigate under /conf folder to the node where policies are stored and you need to add as part of policies manually.
NOTE: In AEM 6.5.5 Onwards this issue can be handled straight forward.
