Unable to move experience fragments from one folder to other in AEM author

[sd55]

Hi,

I have experience fragments created under ''/content/experience-fragments/myproject/myfolder1/experience-fragment-1''.

When I try to move (from sites UI, not from crxde) to location '/content/experience-fragments/myproject/myfolder2' , i get following error

/content/experience-fragments/myproject/myfolder1/experience-fragment-1 (Experience Fragment Template) not allowed below /content/experience-fragments/myproject/myfolder2/experience-fragment-1

Any thoughts on this?
