Apparently MMS floating point values come in several flavours and only one of them is dissected as a float, others just show the hex bytes as displayed in your picture.
However, it looks as if that field does fit the requirements to be dissected as a float, i.e. the first byte is 0x08 and there are 4 other bytes, what version of Wireshark are you using?
Again if you can provide the capture, rather than an image, this can be looked at in more detail, i.e. using a debugger.
