Check your intonation, then just rotate it 180 and/or do the upside down thing and see if there's any difference. Check with Big Island, maybe they can send you a new saddle.
Even if it is a bone saddle or other exotic composite material like Corian, Micarta or Nubone, a new saddle from the maker should not cost you more than $5-10 and maybe another $5-10 for shipping, otherwise you can get a dozen bone saddle blanks for ukulele from ebay or amazon for about $15, and some diamond-grit files and put the blank in a vise and do the work yourself, which is in fact HIGHLY gratifying and meditative for me.
To compensate all 4 strings on a new saddle blank, maybe it takes about 30-45 mins, and is somewhat tedious, to sand it, then fit it back into the uke, then tune up, test the intonation, and if not correct, remove it, put it back into the vise, and then rinse and repeat until it IS correct...
You dont need a PhD to properly compensate a saddle, and nor do you need expensive tools. I use a metal diamond-grit Revlon nail file that cost me $2 at the grocery store and do not even use a vise, I just place it on the top of my desk, and hold it very carefully...but this is an iterative process that you need to go in slow increments, for it you sand off too much, you have to start over with a new saddle blank...you only want to remove like 0.010mm at a time in between re-fitting the saddle after sanding...
However, if you got cash to spend and little time or hand problems, it may be better to pay someone else to do it for you...
I have free time and little extra cash, so I learn how to DIY many things for myself.
