I'm using english UI to get PB tagging work. If a set of passages is followed with "m. fl." then auto detection is out of order. If there is an period in the set of passages then auto detection is working before the period but not after.
In the screen dump below in line one there is a period in the end of passage set and all passages is auto detected.
In line two there is a period i the middle and only the first three passages is auto detected.
In line three there is no period at all and none of the passages is autodetected.

m. fl. is a abbreviation and means "and more" or something like that. You can put it in the end of an uncomplete list.
In spite of running English UI the auto detection will not recognise "Ex 1:26" but Swedish "1 Mos 1:26" is OK. I don't know if this bug is a part of the auto detection problem with Spanish and Swedish UI.
