Indic Romanization from ITRANS keyboard

I use this Installed-keyboard to type on Mac /Google Chrome but lately when I type I am getting extra a letter with diacritic characters. This keyboard works fine on Safari and Firefox browser. How can I fix this issue?

a ā i ī u ū ă e ai ŏ o au ȧ a̐ aḥ >>>text
a aa i ii u uu ae e ai aw o au a.m a.c a.h >>>Keystrokes
a aā i iī u uū aă e aai aŏ o aau a.̇ a.̐ a.ḥ >>>>output

  1. What version of Keyman are using?
  2. What version of macOS are you running?
  3. I’ve just installed the keyboard on macOS Big Sur (11.6 (20G165)), and type out using the keystroke provided here: a ā I ī u ū ă e ai ŏ o au ȧ a̐ aḥ. Everything seems to work just fine on Chrome Version 95.0.4638.69 (Official Build) (x86_64). Help me to reproduce this by probably giving some more details.

2. What version of macOS are you running?
macOS High Sierra, version 10.13.6 Chrome is up to date

Crome /Version 95.0.4638.69 (Official Build) (x86_64)

Keyman version? Are you on the latest stable?

Keyman version?
Keyman 12.0.50 (3).dmg
Google chrome 2.dmg
Also I have no problem in typing on I-pad and other browsers.
May be Google chrome playing game to propagate their Indic input keyboard !

Can you try the latest version of Keyman for macOS (14.0.282 stable)?
