.htaccess mod_rewrite: page name gets repeated multiple times

I use the following code in my .htaccess file to redirect  uppercase letters to lowercase letters in directory names:

RewriteEngine On

RewriteRule ^/?[^\/]*[A-Z] - [E=HASCAPS:TRUE,S=1]
RewriteRule !^/?[^\/]*[A-Z] - [S=28]
RewriteRule ^(/?[^\/A]*)A(.*)$ $1a$2
RewriteRule ^(/?[^\/B]*)B(.*)$ $1b$2
RewriteRule ^(/?[^\/C]*)C(.*)$ $1c$2
RewriteRule ^(/?[^\/D]*)D(.*)$ $1d$2
RewriteRule ^(/?[^\/E]*)E(.*)$ $1e$2
RewriteRule ^(/?[^\/F]*)F(.*)$ $1f$2
RewriteRule ^(/?[^\/G]*)G(.*)$ $1g$2
RewriteRule ^(/?[^\/H]*)H(.*)$ $1h$2
RewriteRule ^(/?[^\/I]*)I(.*)$ $1i$2
RewriteRule ^(/?[^\/J]*)J(.*)$ $1j$2
RewriteRule ^(/?[^\/K]*)K(.*)$ $1k$2
RewriteRule ^(/?[^\/L]*)L(.*)$ $1l$2
RewriteRule ^(/?[^\/M]*)M(.*)$ $1m$2
RewriteRule ^(/?[^\/N]*)N(.*)$ $1n$2
RewriteRule ^(/?[^\/O]*)O(.*)$ $1o$2
RewriteRule ^(/?[^\/P]*)P(.*)$ $1p$2
RewriteRule ^(/?[^\/Q]*)Q(.*)$ $1q$2
RewriteRule ^(/?[^\/R]*)R(.*)$ $1r$2
RewriteRule ^(/?[^\/S]*)S(.*)$ $1s$2
RewriteRule ^(/?[^\/T]*)T(.*)$ $1t$2
RewriteRule ^(/?[^\/U]*)U(.*)$ $1u$2
RewriteRule ^(/?[^\/V]*)V(.*)$ $1v$2
RewriteRule ^(/?[^\/W]*)W(.*)$ $1w$2
RewriteRule ^(/?[^\/X]*)X(.*)$ $1x$2
RewriteRule ^(/?[^\/Y]*)Y(.*)$ $1y$2
RewriteRule ^(/?[^\/Z]*)Z(.*)$ $1z$2
RewriteRule ^/?[^\/]*[A-Z] - [N]
RewriteCond %{ENV:HASCAPS} TRUE
RewriteRule ^/?(.*) /$1 [R=307,L]

Select allOpen in new window

The problem is that the page name gets repeated.

/HeLLO/WoRlD.html
gets redirected as:
/hello/WoRlD.html/WoRlD.html/WoRlD.html/WoRlD.html
