[GeoNetwork-users] Problem entering/displaying bilingual metadata

We have multilingual (Eng/Fra) MCP metadata records (one such snippet follows). It appears to be entered into our GeoNetwork 2.6.4 server correctly, but it does not display the French version of title, abstract and purpose upon request. (A combined English-French abutted title does appear in a search, as " BATHYMETRY OF ROBERTS BANK TURNING BASIN, 1996 BATHYMÉTRIE DU BASSIN D'ÉVITAGE ROBERTS BANK, 1996").
Can someone please tell me if:
a) there are any fundamental metadata creation issues (especially with the 'locale' code block or the title|abstract|purpose blocks), or
b) perhaps we are not understanding or not properly implementing the display of the metadata (server implementation problem)?
The xml code seems okay, and the record was validated and then entered without error.
If the problem is with the display xslts upon output, is there a place to start looking, or some English/French xslts already available?

And later in the record:
