Calculator on iPAD changes MDSM

Odd one here...

Several of the calculators on the iPAD change the MDSM - to Netaux for example...

-- Anyone else found this?
-- Anyone found one that does not (they are almost all called 'calc' something so not sure how easy it is to know what you have!?)

Very very odd...

Nothing else wrong with network, separate switches, wap bla bla etc etc

Thx.
