Description
It seems like the Log Browser is ignoring the units for onboard logs files (the FMTU messages). For example the CTUN.DCRt and CTUN.CRt fields (desired climb rate and climb rate) should be displayed in m/s but instead they are appearing in cm/s
Below is a log from a simple flight in SITL where the vehicle climbed and descended at 2.5m/s. Instead we see 250.

Here are a couple of sample log files https://www.dropbox.com/scl/fi/yvdldhdhcnzpx0tzwot1e/45-and-47-logs.zip?rlkey=solrmqjv453qz7zglqevhkdau&dl=0
I feel like this use to be displayed correctly

Research direction
Start in the Mission Planner Log Browser and trace how onboard log FMTU messages are used for CTUN.DCRt and CTUN.CRt display units. Reproduce with the linked sample logs or the described SITL flight; done means these values appear in m/s rather than cm/s.
