[TYPO3] no TemplaViola in File's context menu after installing DAM

[Bing Du]

Hi,

Typo3 V4.0.2
templavoila 1.1.0
dam_tv_connector 0.0.7
DAM 1.0.5
dam_ttcontent 1.0.1
dam_filelinks 0.3.7
css_filelinks 0.2.10

Before installing DAM, in File->Filelist, if I clicked the folder icon
next to any file, I could see 'TemplaViola' as an option along with other
file operations (Edit, Delete, etc.) in the popup context menu.  After
installing DAM, in Media->File, the folder icons are not clickable
anymore.  How should TemplaVoila be accessed in DAM?

Thanks in advance,

Bing
