Are you using a 10 stop? Looks like it's causing reflection.
is there anything i can do to prevent light leak?
what are you trying to achieve with 5 mins exposure?

2nd those who asked why you will need 5 minute exposure.
There are many possibilities. One question I have is the compatibility of your holder and the filters you used. Gaskets provided by the filters may not match your holder if they did not come from the same source. I also seen some sellers in the market didn't even apply gaskets to 10 stop filters!
Could you let us know more specifics about the lens you use, the filter holder you have too?
If not, work with the shop that you got this from? If they are selling you these filters, I have to assume that they should be cluey enough to help you out.
using lee holder and haida 10 stop filter with gmask put on size is 100mm
