R help - Jul 2015 - Same results in arules after changing support and confidence

Hello, everyone!

I'm new to R, so I'm sorry in advance if it's something obvious, but
I still
can't figure it out.

I've started experimenting with apriori and everything was working fine,
i.e. I changed support and confidence and results were different depending
on combination.

But on the next after running the same code and same dataset I'm getting 0
rules no matter which combination I'm using. 

My dataset looks like this (foodmarket data):

Trans_Id,Product
3694728,Washington Berry Juice
3779788,Washington Berry Juice
4146666,Washington Berry Juice
4405313,Washington Berry Juice
etc.

My code is:

library('arules')
transactions <-
read.transactions(file="transactions.csv",format="single",sep=",",cols=c(1,2),rm.duplicates="false")

basket_rules <- apriori(transactions, parameter = list(sup = 0.05, conf 0.01,
target="rules",minlen=2))

With following results:

And another one with different parameters but same result:

So, I have no idea how is that possible. Any input will be appreciated.

Thank you.
