Security deposit configured but still malfunctioning.

I have configured my security deposit to $100. I had it at $500 previously. But when taken to the security deposit form it wants $500. It also shows up as $500 when I insert a field. What's the problem?

When you change your security deposit amount setting, that will apply to new bookings, but, it will not change the security amount setting for bookings that previously existed.

That was just an example. I understand it won't change old ones. I figured out what I did wrong though. In the end, I think I've come to the conclusion that a PMS is not for me. There are just so many limitations and issues with integration that it's not worth the headache. Maybe someday when these companies want to work with each other but not for me.
