Bug in transition to Devanagari character ॥

[ijya]

I am encountering a strange bug where the transition to the Devanagari character ॥ does not happen if it is immediately preceded by any other character. A MWE:

\documentclass{article}
\usepackage{fontspec}
\setmainfont{Latin Modern Roman}
\newfontfamily\s[Script=Devanagari]{Shobhika-Regular}
\usepackage[Devanagari,Latin]{ucharclasses}
\setTransitionsForDevanagari{\s}{\rmfamily}
\begin{document}
त ॥६३॥ \\
There seems to be some bug in the transition to the second ॥ character in the above and below lines. 
I have not encountered this issue with any other character. \\ 
॥क॥ क \\
The bug does not appear if there is a space before the second ॥ character:\\
॥क ॥ क
\end{document}

I would just like to add that there is no problem if ucharclasses is not employed and we just use {\s त ॥६३॥}
