Good catch. !!
Yeah lohit 2.5.4 had some issues from standards perspective. We worked on
Lohit Malayalam under lohit2 project [1] in last couple of months and did
alpha [3] and beta [2] release. Bugs you are pointing is already fixed in
2.92.0 release.

 Lohit Malayalam 2.92.0 looks very stable not found any bugs in last 1
month. I was about to ask you if you can review lohit malayalam 2.92.0 and
let us know if we are missing any important thing. Will be very helpful for
lohit2 project.

Best Regards,
