From time to time will not calculate proper BPM

From time to time, i have had a 130 bpm track come up as 100-106 BPM. This is not a problem as far mixing goes, I can beat match without a BPM counter however, when looping the wrong Calculated BPM track it will not loop seemlessly, this is a problem as a lot of my mixing is done by caring the last track into the next track in a loop for as long as harmonically possible. Is there a way to go back and have the program recalculate the BPM. I have noticed once the program has done the calculation once it will never recalculate on it's own, even when shutting down and restarting. the only way around this i have found is re-installing the program and this is a pain in the ass.
No big deal just looking for a hint.
Furthermore this is a very isolated issue.
