Unoff 4.4.4 CM/LOS11 20170130 filemanager 2.0.0 can't copy/cut

[1stStep]

Hi all
I just installed this ROM, all is great except I can't move files from/to internal to/from external SdCard. I can create & delete on both side.
Do you have this too or did you workaround.
Maybe this my phone that is dead, because I have the same issue from ubuntu :

libmtp error : unknown error.

They have a very old ticket in their lauchpad, so I don't know what to think, and guys on github for mtp support say it would be better if we still had good old standard UMS.

I did : Select then Cut (usual way for me since DOS2.0 :cyclops: ) and immediately got the error "Operation not allowed in current folder".
Okay I write down the good way here for newbs that may find this:
There "Select" IS "Copy" (the menu only shows Paste and Cut what is puzzling). Then browse to destination, and only now choose Paste to make a copy, or Cut to move the previously selected item.
