VolumeFreeSpace full prune not kicking in on trigger after upgrade to 1.28.0

[amplicity]

Description
After upgrading to 1.28.0, my VolumeFreeSpace prune trigger does not seem to kick in. According to df -h, i have 347G. My threshold is set to 370000 MB.

Steps to Reproduce
Here is my current startup command:

 ./nethermind --config mainnet --JsonRpc.Enabled true --HealthChecks.Enabled true --HealthChecks.UIEnabled true --Pruning.Mode Hybrid --Pruning.FullPruningTrigger VolumeFreeSpace --Pruning.FullPruningThresholdMb 370000 --JsonRpc.JwtSecretFile='jwt.hex'

Actual behavior
Pruning does not kick in. I checked logs and see no mention of "Full Pruning" or "Full Prune".

Expected behavior
It should have been pruning.
