Hi,
you should use syntax like
5|opt1
10|opt2
.....
if you have some problem due to right-to-left syntax, you can always use language constants, so options become like:
5|OPTION1
10|OPTION2
.....
you can translate constants OPTION1,OPTION2,.... with Joomla language override system:
- Go to Extensions->Languages->Overrides
- Click to "New" button
- Fill constant with "OPTION1"
- Fill translation and save
Language constants are useful also to translate various options in different languages
