(at tags it works perfect)
You'll need to use custom_columns_settings in personal.ini instead of the Custom Columns tab settings and use the 'a' mode.

Spoiler:
Code:
## (Plugin Only) - You can also populate calibre custom columns with
## the site specific metadata using custom_columns_settings (but only
## if 'Allow custom_columns_settings from personal.ini' is checked in
## the plugin GUI config.)  There are three parts, the entry name,
## then the label of the calibre custom column, then (optionally) a
## 'mode'.  'r' to Replace any existing values, 'a' to Add to existing
## value (use with tag-like columns), and 'n' for setting on New books
## only.  (Default is 'r'.)

## Literal strings can be set into custom columns using double quotes.
## Each metadata=>column mapping must be on a separate line and each
## needs to have one space at the start of each line.

## 'r_anthaver' and 'n_anthaver' can be used to indicate the same as
## 'r' and 'n' for normal downloads, but to average the metadata for
## the differents story in an anthology before setting in integer and
## float type custom columns.  This can be useful for a averrating
## column, for example.  Default is to sum the values of all stories,
## and numChapters and numWords are always summed.

#custom_columns_settings:
# cliches=>#acolumn
# themes=>#bcolumn,a
# timeline=>#ccolumn,n
# "FanFiction"=>#collection
# averrating=>#averrating,r_anthaver
