<h3>Description</h3>
<p>Recently I upgraded kamailio to 5.4.2 using the dlgs module. No matter how many calls I make, the dlgs_count() and dlgs_tags_count() always return 1. After viewing the source code, I found the following bugs</p>
<h3>Troubleshooting</h3>
<h4>Reproduction</h4>
<p>dlgs_init($fu,$tu,"data");<br>
dlgs_update();<br>
dlgs_count("any","eq","1");<br>
and then make several calls, the dlgs_count always return 1.</p>

<h3>Possible Solutions</h3>
<p>I find the <code>ki_dlgs_count</code> functions always return  1;<br>
<a target="_blank" rel="noopener noreferrer" href="https://user-images.githubusercontent.com/26111722/100605735-55308280-3343-11eb-9908-aa8f55e60f63.png"><img src="https://user-images.githubusercontent.com/26111722/100605735-55308280-3343-11eb-9908-aa8f55e60f63.png" alt="image" style="max-width:100%;"></a><br>
I modified the retrun value = 10086, then the <code>dlgs_count</code> always return 10086 ! !<br>
I modified the return value = dlgs_count(msg, vfield, vop, vdata); then I found the dlgs_count always return 0; obviously there is still something wrong.<br>
then I run the dlgs_ht_dbg() in the dlgs_count (dlgs_records.c) and get some useful dbg log as above.<br>
as the picture shows，the slots[i].astats.c_init is always 0 or -1.  I think maybe c_init is not initialized to 1 when dlgs_init . and I add the c_init's initial logic in the dlgs_add_items()  then  everything is fine !</p>
