I am using Notepad++ version 6.5.3 (Unicode) and have the TabIndentSpaceAlign plugin (version 1.0) installed, and it appears in the drop-down list available from the Plugins menu in the toolbar.
However, Plugin Manager (version 22.214.171.124) does not include TabIndentSpaceAlign in its 'Installed' tab; instead it includes it in its 'Updates' tab, noting that the installed version is 'unknown' and that version 1.0 is available.
Even if I opt to install the reported update and allow Notepad++ to restart, Plugin Manager still insists the plugin is not installed and continues to offer the update.
Any ideas as to what is going on here?
