Yours is for sure the earlier version of the Modular 45 straps, which is too long. The size of the straps was later updated by TAG Heuer, although keeping the same part numbers. So when buying online, it’s important to be sure that you will receive the updated version, just asking the length of the shortest half of the strap.
In this picture you can see both versions side by side. The shortest half of the strap measures around 7.5cm in the updated, and around 9.5cm in the early version
