FRRR vs FRER

So

Ok, so according to the interwebs FRERs (early results) are supposed to be more sensitive than an FRRR (rapid results). I have had progressing lines on the FRERs, but they arent super dark yet. Took a FRRR just for kicks this morning in addition to an FRER and the rapid response test (supposedly less sensative) is actually darker than the early resulta test...has anyone ever seen this before? Ive seen posts about the opposite occuring, but never the less sensative test showing up more positive looking. Pic below!
