cutadapt problem

[gfmgfm]

Hi all,

I have the following problem with cutadapt: I ask to remove an adapter only once, but it removes it more than once.

The read:
TTCCACTTGAGTCCAGGGTGCGTACGCTGCAGGTCGACTCCAC

The command:
cutadapt -n 1 -a TCCAC -e 0.2 my_file.fastq

The result:
is a read with:
T (the TCCAC in the begining - is also used - and this leaves only T).

Is this a bug?

Any suggestions how to overcome this will be appreciated.
