I have what may be a similar problem.
See if
(a) all the settings are reset and not just those you've modified
(b) if the id for that device changed after sleep/wakeup.
To find your touchpad id run:
$ xinput list
and you should get something like
⎡ Virtual core pointer id=2 [master pointer (3)]
...
⎜ ↳ SYNA307B:00 06CB:CD46 Touchpad id=15 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=19 [slave pointer (2)]
...
Then to see what the settings are run
$ xinput list-props 15
Device 'SYNA307B:00 06CB:CD46 Touchpad':
Device Enabled (184): 1
Coordinate Transformation Matrix (186): 1.000000, 0.000000, 0.000000,

libinput Horizontal Scroll Enabled (374): 1
and you can see if they change before/after wake sleep.
For me there's a workaround from a kernel bug where i2c_hid drivers cause
interrupts for the Touchpad to go nuts on sleep/resume (modprobe -r/modprobe)
but it causes xinput settings to be lost and the Device IDs
to change on sleep/resume. If that's your case too then you can create a
systemd script file to use on resume from sleep that executes something like
"xinput 'device_name_here' 'libinput Tapping Enabled' 1"
(or whatever your setting is) to restore the xinput settings you had before
sleep.
