I have two conditions with 2 and 3 biological replicates, I made a dba object like this:

k4 <- dba.count(k4, minOverlap = 2)

k4 <- dba.contrast(k4, categories = DBA_CONDITION, minMembers = 2)

k4 <- dba.analyze(k4, bSubControl = FALSE)

olap.rate <- dba.overlap(k4, mode = DBA_OLAP_RATE)

[1] 17534 17534 17534 17534 17534

for some reason I get the same number of peaks for each replicate/treatment...

when I use plotVenn 

  dba.plotVenn(k4 ,k4$masks$Consensus & k4$masks$WT)

I get different numbers for each replicate.

Don't know if it matters but I have duplicated peaks in my BED file (with different scores).

Hope that Dr. Stark could help me with that...

You should change your tag to diffbind so the author sees your question. Also show the output of sessionInfo().
