Hi Philip.
In a trend analysis, each test is orthogonal (independent) of the other
tests so the results reported are quite reasonable. Admittedly, in my
experience at least, it's a little unusual to have 4 out of the 5 trends
significant but such a finding does not indicate any problem with the
analysis. Are there equal intervals between the six levels of your factor?
